SCCM Troubleshooting : Ironing out Patching for ConfigMgr 2007 (upto 95% compliance)

This guide will take you through troubleshooting guides, tips, tricks and tools to achieve 95%+ compliance in your environment and maximum coverage. The guide assumes the following environmental conditions:

Microsoft System Center Configuration Manager 2007 R3

WSUS 3.0 SP2 used as base for Software Updates

Windows Client endpoints

Three tier SCCM hierarchy

SCCM Side Clean-up

Obsolete

Obsolete clients are those that have been replaced by new ones. This usually happens during refresh OS deployments where the hardware stays the same and thus the hardware id is the same but the SMS GUID changes because the OS has been reloaded or the GUID is regenerated for another reason but the hardware remains the same.

Reasons – 1. Hard disk swapping 2. Renaming machines 3. Reimage OS 4. Reinstalling SMS/SCCM agent on the machines without proper uninstall.

If machines is showing up as Obsolete – that is good to delete, manually or via scheduled task within SCCM

No Client

Identify machines where they show up as no client,

If Client = NO and Site Code = blank – this indicate machine is not belonging to a particular boundary and it needs to be defined.

Inactive

Inactive client s are those that have not been discovered recently by the heartbeat discovery. The definition of recently is defined in the delete task as a number of days. Please note that obsolete client s are also marked inactive.Reasons– Offline machines 2. Machines having DNS issue/No name resolution 3. Machines are in inventory stock

Refer the collection created via #WQL1 , machines are good to clean-up if Inactive=YES,

Duplicate – these are variants of obsolete, or outcomes of causes as explained in obsolete.

To find duplicate entries – create a collection with the following WQL query >

Reference : #WQL1

select R.ResourceID,R.ResourceType,R.Name,R.SMSUniqueIdentifier, R.ResourceDomainORWorkgroup,R.Client from SMS_R_System as r full join SMS_R_System as s1 on s1.ResourceId = r.ResourceId full join SMS_R_System as s2 on s2.Name = s1.Name where s1.Name = s2.Name and s1.ResourceId != s2.ResourceId

Based on the results – machines which are good to be deleted if Obsolete = YES.

Unapproved – These as long as site code and domain are correct – good to be approved

Unknown domain

Machines reporting in from unknown domain could mean

Machine disjoin from current domain and rejoined another

Machine from another domain received incorrect SCCM client installation/push

Machines from other domain are using incorrect installation switches

Unknown hostname naming format

Most multi-national organizations follow standards to maintain machine naming based on region and country

APDDSERIALNUMBER = AP – APAC, DD – Desktop

NALLSERIALNUMBER = NA – North America, LL – Laptop

Any deviation from these naming standards means the machine should not be in SCCM.

Site to Site Communication

Verify SCCM site communication is healthy.

Create test collections/packages on Central Site and then view on the Primary Sites

Verify machines reporting in Primary are available on Central – dump ‘All Systems’ from both and do vlookup to find out GAP.

Run preinst syncchild SITECODE against any primary not in sync.

Discovery Configuration

Confirm that the correct OU’s are being queried within Active Directory, any new additions or new OU’s need to be sync’ed with AD team.

Heartbeat discovery is enabled and configured for weekly [mild] – daily [aggressive/urgency]

Distribution Point / DP Group

A good sanity check is to target a test package to all DP groups and in the review window analyse which distribution points did not get selected.

Verify the Deployment Packages are targeted to all active distribution points – this helps attain maximum coverage, so machines from every corner of the infrastructure get the necessary patches.

Site Info v/s WSUS Infra

For keeping a tidy sync between WSUS and SCCM – depending on your SCCM SUP’s spread – you can compare WSUS downstream servers v/s the built-in report 75 of SCCM.

http://servername/SMSReporting_sitecode/Report.asp?ReportID=75

WSUS Sync up to date

Check last sync between downstream and upstream partners – if there is a gap that needs to be rectified.

Top Down Checks

Start the checks on the WSUS console from top to down – start from Central and then check on the primaries – make sure all servers are reporting in and have latest sync.

Autonomous WSUS

Verify none of the WSUS downstream partners are showing up as Autonomous.

If they are fix with this method

Check site to site replication Sitectrl - parent settings Sitectrl file exchange Pointing to self for updates Upstream server checkbox ConfigMgr side configuration flip and flipback

Windows Update Agent Version

Windows Update Agent version differences in the environment can cause issues.

Machines with older versions of WUA will not be able to sync latest updates or different products.

Use following SQL Statement to make a custom report >

SELECT v_R_System.Netbios_Name0, v_GS_WINDOWSUPDATEAGENTVERSIO.Version0 FROM v_GS_WINDOWSUPDATEAGENTVERSIO INNER JOIN v_R_System ON v_GS_WINDOWSUPDATEAGENTVERSIO.ResourceID = v_R_System.ResourceID WHERE v_GS_WINDOWSUPDATEAGENTVERSIO.Version0 <> 'ISNULL' ORDER BY v_GS_WINDOWSUPDATEAGENTVERSIO.Version0

The result would indicate disparities between the WUA versions in the environment and these can be targeted.

Push the latest WUA to these machines.

Make sure kb2734608 is installed on all WSUS servers

Push latest WUA – http://ift.tt/2uNI8fZ

Windows Update Agent Repair

Use the WUA from http://ift.tt/2uNI8fZ to repair broken Windows Update Agents on machines – with unique scan errors etc and also helps machines which are unable to update the WUA.

WOL – Wake on Lan

Utilize SCCM’s most underrated/underutilized feature – Wake On Lan. This benefits in patching – so that machines can be woken up and then patched and they get auto rebooted as per requirement. This benefits in reaching out to machines in off hours – times when users are not present – great to combine with ‘Maintenance Windows’. This way you will get to set a time for when these machines will receive the patches (offhours) + ability to wake them up for the activity. Reduces load on the network and off hours maintenance is always appreciated.

State Message Drop

Evaluations from machines sometimes are not reported in correctly, machines at times have the patches installed but same does not reflect in the compliance reports. This is caused due to drop in state messages from client to server, or from server to server and at times shows up as Enforcement State Unknown.

There is a method to trigger the full state message to be sent from client to server >

Option Explicit On Error Resume Next Call RefreshServerComplianceState ' WScript.Echo "Finished" Sub RefreshServerComplianceState() dim newCCMUpdatesStore ' Create the COM object. set newCCMUpdatesStore = CreateObject ("Microsoft.CCM.UpdatesStore") ' Refresh the srvr compliance state by running the RefreshServerComplianceState method. newCCMUpdatesStore.RefreshServerComplianceState ' Output success message. 'wscript.echo "Ran RefreshServerComplianceState." End Sub

This script can be found on the web in various places and simply makes use of the SCCM SDK to cause the client to resend it’s data to the MP. It’s a convenient way to force some state messages up so we don’t have to wait on components to insert them.

Typically, a vb script is executed simply by using cscript as show below. But note that this fails. I show this to illustrate the problem you might see if trying to run the script yourself. SCCM is a 32 bit application but, in this case, running on a 64 bit server. The default version of cscript is the 64 bit version – and generally this works fine with any vbscript. In this case, however, the call being made requires the 32 bit version of cscript which you must run out of the syswow64 folder as shown in the second example.

At this point we have to wait for the next state message polling cycle which will cause all state messages to be sent back up.

Our polling cycle has now fired and if we look at the statemessage.log we see that the state information has been pulled, formatted (into XML) and sent to the MP.

<![LOG[StateMessage body: <?xml version="1.0" encoding="UTF-16"?> <Report><ReportHeader><Identification><Machine><ClientInstalled>1</ClientInstalled><ClientType>1</ClientType><ClientID>GUID:F1B03089-9EA1-4A64-83DC-5F8E77BDDEB4</ClientID><ClientVersion>4.00.6487.2000</ClientVersion><NetBIOSName>STEVERAC64-2</NetBIOSName><CodePage>437</CodePage><SystemDefaultLCID>1033</SystemDefaultLCID></Machine></Identification><ReportDetails><ReportContent>State Message Data</ReportContent><ReportType>Full</ReportType><Date>20110107184030.662000+000</Date><Version>1.0</Version><Format>1.0</Format></ReportDetails></ReportHeader><ReportBody><StateMessage MessageTime="20110107183046.153000+000" SerialNumber="1431"><Topic ID="21e49ac6-a273-4a61-9794-eb675bc743e5" Type="500" IDType="3"/><State ID="2" Criticality="0"/><UserParameters Flags="0" Count="1"><Param>102</Param></UserParameters></StateMessageserParameters></StateMessage></ReportBody></Report> ]LOG<![LOG[CStateMsgManager::GetSignEncyptMode]LOG]!><time="12:40:31.037+360" date="01-07-2011" component="StateMessage" context="" type="1" thread="3592" file="statemsg.cpp:1820"> <![LOG[Successfully forwarded State Messages to the MP]LOG]!><time="12:40:31.099+360" date="01-07-2011" component="StateMessage" context="" type="1" thread="3592" file="statemsg.cpp:1527">

I’ve truncated the XML due to size – leaving only a single state message – we will come back to the XML shortly as it really isn’t very friendly in this format.

Note that although the statemessage.log records that the messages have been dispatched to the MP, the statemessage system doesn’t actually do the movement of data to the MP – CCMExec does that as we see from the small snip below. There is actually a bit more that goes on behind the scenes at this point but it’s sufficient to know that CCMExec sends data to the MP – in this case the MP_Relay component.

<![LOG[OutgoingMessage(Queue='mp_mp_relayendpoint', ID={A9E7A07D-223D-4F5D-93D5-15AF5B72E05C}): Delivered successfully to host 'STEVERACPRI.STARTREKNG.COM'.]LOG]!>

Switching to the MP now, when data arrives for processing at MP_Relay (again, a bit more behind the scenes stuff happens but not worth diving into here since most folks will never come across a need to dig in) we see the data processed and translated to .SMX file format and placed in auth\statesys.box\incoming.

Inv-Relay Task: Processing message body Relay: FileType= SMX Relay: Outbox dir: C:\Program Files (x86)\Microsoft Configuration Manager\inboxes\auth\statesys.box\incoming Relay: Received 0 attachments Relay: 0 of 0 attachments succesfully processed Inv-Relay: Task completed successfully

If we take a look at the auth\statesys.box\incoming directory – and if we are fast enough – we will see the .SMX files there and being processed. Typically you won’t see much here – if you do it’s worth investigating what messages are here and not being processed. If we find a .SMX and crack it open with notepad we can see the detail but the formatting leaves much to be desired.

A little trick here. If you rename the .SMX and simply add a .XML extension – so <filename>.SMX.XML and double click it you get a much nicer formatting of the data through IE. I’ve highlighted the info in the file that is key – we can easily see the machine details and also state message details we have become familiar with – and also the unique state message ID.

Note: If you are going to rename these files then you should copy them out first so you aren’t impacting the statesys.box folder itself.

From here all that remains is to process these state messages into the database. You can see these messages processed in the statesys.log – something similar to the following.

Found new state messages to process, starting processing thread Thread "State Message Processing Thread #0" id:5076 started CMessageProcessor - Detected parent site 'CEN' CMessageProcessor - Processing file: mdlbp169.SMW CMessageProcessor - Processed 1 records with 0 invalid records. CMessageProcessor - Successfully replicated file "mdlbp169.SMW" to parent site CEN. CMessageProcessor - Processed 1 message files in this batch, with 0 bad files. Thread "State Message Processing Thread #0" id:5076 terminated normally

The DB processing component often can be seen by enabling SQL tracing. That doesn’t help much here so we turn to SQL profiler – which does give us a hint at what is happening but still doesn’t’ completely pull back the covers. Suffice it to say that there are a number of SQL stored procedures responsible for processing state messages – and also a number of tables in the database that store state message data. The stored procedures that do the state message processing generally start with the name spProcess – there are a number of them. Those interested should be able to dig in further from here to see the tables involved, etc.

OK, with processing into the DB complete we have finished the state message process flow – well, almost. The last thing to discuss is state message resyncs.

I have already alluded to the fact that the site server keeps track of state messages as they come in – so that if any state messages are missing they can be flagged and a resync requested from time to time. State messages and their data are important so we definitely don’t want to miss any.

As state messages come in the unique ID is read and stored in the database. As processing continues this data is constantly updated and if a gap is detected we flag it and store any missing state messages in the SR_MissingMessageRanges table. One would hope that this table will be empty but in production we may see data in the table here and there. This table is used to help keep track of state messages needing resync.

Any needed resyncs are evaluated hourly – but that does not mean that systems will be running a resync hourly. The site control file specifies a few settings of interest (with the site control file always apply the caution – look, don’t touch! )

BEGIN_COMPONENT <SMS_STATE_SYSTEM> <6> <STEVERACPRI> PROPERTY <Loader Threads><><><4> PROPERTY <Inbox Polling Interval><><><900> PROPERTY <Loader Chunk Size><><><256> PROPERTY <Max Chunks Fetched><><><100> PROPERTY <Resync Check Interval><><><60> PROPERTY <Min Missing Message Age><><><2880> PROPERTY <Heartbeat Msg Interval><><><15> END_COMPONENT PROPERTY <Resync Merge Interval In Hours><><><72>

Resync Check Interval is set to 60 minutes – this is the schedule at which we check for any systems needing state message resyncs.

Min Missing Message Age is set to 2880 – this is the amount of time a message has to be missing before a resync is requested.

Resync Merge Interval in Hours is set to 72 – this is the amount of time between resyncs of a client. This interval helps ensure that clients won’t resync over and over again. You should not see a client resync more frequently that the interval set here.

WSUS automated cleanup via powershell

http://ift.tt/2uNK2NE

This little script will perform a clean up of declined and superceded updates in the WSUS database. It uses the .Net class “Microsoft.UpdateServices.Administration” assembly, which should be loaded on your WSUS server.

Note that this script will stop the WSUS service twice, but these services will be restarted correctly by the script, and no user action is needed.

# Performs a cleanup of WSUS. # Outputs the results to a text file. $outFilePath = '.\wsusClean.txt' [reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null $wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer(); $cleanupScope = new-object Microsoft.UpdateServices.Administration.CleanupScope; $cleanupScope.DeclineSupersededUpdates = $true $cleanupScope.DeclineExpiredUpdates = $true $cleanupScope.CleanupObsoleteUpdates = $true $cleanupScope.CompressUpdates = $true #$cleanupScope.CleanupObsoleteComputers = $true $cleanupScope.CleanupUnneededContentFiles = $true $cleanupManager = $wsus.GetCleanupManager(); $cleanupManager.PerformCleanup($cleanupScope) | Out-File -FilePath $outFilePath

Client Actions Tool | http://ift.tt/2wdtKBh

Description SCCM Client Actions Tool or SCCM CAT is a practical and simple HTA application for performing most common day-to-day administrative tasks on System Center Configuration Manager 2007 clients. The tool allows running actions remotely on one or more computers. A list of computers can be provided either from a file (XLS, XLSX, CSV, TXT), loaded from SCCM collection or simply entered as a text into a text area. The main goal for creating this tool was to have something simple that doesn’t have any prerequisites and doesn’t require installation. Just pick it up and run. It’s an alternative to SCCM console and right-click tools because it’s not always possible to install SCCM console everywhere and manage clients in closed environments. The features are as follows:

Initiate most common SCCM client schedule actions.

Initiate various actions to manipulate SCCM client agent. Install/uninstall agent, change GUID, assign site code, change cache size, etc.

Initiate SCCM client health checks and fixes. Allows running checks with and without fixes as well as full health check.

Initiate various administrative actions on workstations. Copy a file to remote computers, refresh policies, reset security settings, wake on LAN, etc.

Query for different values from remote computers. Query for wide range of information such as current management point, available advertisements, logged-on user, WSUS server, WUA version, patch status, system uptime, reboot pending state, etc.

Switch between integrated authentication and alternate credentials. Supports using multiple credentials. When logged on username has not enough rights it’s possible to specify alternate credentials by clicking on a link in top-right corner. Windows XP requires that cmdkey.exe is available in HTA folder.

Check for newer versions of the tool on startup.

Automatically install SCCM client during health check in case version is too old or agent does not work. Optional feature that can be enabled in configuration file.

Save list of offline computers for later use. Optional feature that can be enabled in configuration file.

Easily configure client installation properties. Ccmsetup.exe command line can be created dynamically by using GUI controls.

Use TXT, CSV, XLS or XLSX files as the data source. Files with TXT extension must have computer names on each line. Excel worksheets are read from column A starting from second row and it’s possible to write results back to worksheet. Using exported CSV from SCCM console is also supported.

Populate computer list from SCCM collection. Allows loading all collection members into a list.

Manually enter computer names into a textbox. Allows manually entering one or more computers in a text box for quick actions.

Supports both 32-bit and 64-bit OS on clients.

Supports Windows XP SP2 and newer operating systems on clients.

Displays real-time progress. Works when running HTA on Windows 7 or Windows Server 2008. Useful when there are thousands of computers and it would be nice to know how much is done. HTA window may not update as smoothly in Windows XP and Windows Server 2003, but it works.

Log is created in a text area and in a file. Lastlog.log is written to HTA folder. By default the log is using Trace32 log formatting. Log can be opened directly in application. It’s also possible to keep log history.

Uses configuration file to store default settings.
