Adjusting the ConfigMgr Script Execution Timeout (pre 1810)

, , , , ,

In ConfigMgr, scripts that execute default to having an execution timeout of 60 seconds.  Normally this timeout is fine but you may run into situations where scripts run long and clients start receiving the following error in DcmWmiProvider.log.

In-line script execution time-out…
Failed to process CScriptProvider::PutInstanceAsync.
The script execution has timed out. (Error: 87D00321; Source: CCM)

ConfigMgr 1810 introduced the option to set the script timeout, if you are not up to 1810 yet and need to adjust the timeout then you are in the right place.  User raphael at posted a blog on how to adjust the timeout, this is a good script for a single site infrastructure but the client setting does not flow down from a CAS to primary sites.  For this reason I adapted his original script to handle a multi-level site hierarchy.  Update the variables at the top of the script as required and run it to set the script execution timeout.

$SiteCode = "CM1"
$SiteServer = ""
$ScriptTimeout = 120
$CCMAgents = (gwmi -Namespace root\sms\site_$SiteCode -Class SMS_SCI_ClientComp -ComputerName $SiteServer | where {$_.ClientComponentName -eq 'Configuration Management Agent'})
foreach ($CCMAgent in $CCMAgents)
    $props = $CCMAgent.Props
    for ($i = 0; $i -lt $props.count; $i++)
        if ($props[$i].PropertyName -eq "ScriptExecutionTimeout")
            $props[$i].Value = $ScriptTimeout
    $CCMAgent.Props = $Props

Keeping the SCCM Cache Clean with DCM

SCCM Cache Clean

In environments with frequent software distributions the SCCM cache folder can quickly take up large amounts of disk space.  This really becomes problematic on older systems or virtual machines with limited amounts of disk space.  Our support team found themselves having to constantly track down systems with low disk space and clean the cache.  I came up with this DCM configuration item to automatically detect and cleanup content in the cache which is older than the given number of days.  The detection and cleanup scripts both write to their own application event logs so you can see a history of cleanup activities.

Creating the CI

Create a new configuration item and select Windows Desktops and Servers as the type of configuration item.

Choose the appropriate operating systems.  In my case I selected all operating systems as I wanted the cache to be cleaned across the board.

Create a new setting and set it’s type to script and data type to string.

Add a discovery script for detecting old items in the cache folder.  Customize the number of days as you see fit.  You can also modify the event log source if desired.

$MinDays = 30
New-EventLog -LogName SCCM_Cleanup -Source "DCM" -ErrorAction SilentlyContinue
Write-EventLog -LogName SCCM_Cleanup -Source "DCM" -EntryType Information -EventId 1000 -Message "Detection starting for Cleanup CCMCACHE" -ErrorAction SilentlyContinue
$UIResourceMgr = New-Object -ComObject UIResource.UIResourceMgr
$Cache = $UIResourceMgr.GetCacheInfo()
$count = ($Cache.GetCacheElements() | where-object {[datetime]$_.LastReferenceTime -lt (get-date).adddays(-$mindays)} | Measure-object).Count
Write-EventLog -LogName SCCM_Cleanup -Source "DCM" -EntryType Information -EventId 1003 -Message "Total obsolete items found: $count" -ErrorAction SilentlyContinue
Write-EventLog -LogName SCCM_Cleanup -Source "DCM" -EntryType Information -EventId 1001 -Message "Detection ending for Cleanup CCMCACHE" -ErrorAction SilentlyContinue

Next, define a remediation script.  Once again you can customize the number of days and event log name.  The number of days should match your detection script.

$MinDays = 30
New-EventLog -LogName SCCM_Cleanup -Source "DCM" -ErrorAction SilentlyContinue
Write-EventLog -LogName SCCM_Cleanup -Source "DCM" -EntryType Information -EventId 1010 -Message "Remediation starting for Cleanup CCMCACHE" -ErrorAction SilentlyContinue
$UIResourceMgr = New-Object -ComObject UIResource.UIResourceMgr
$Cache = $UIResourceMgr.GetCacheInfo()
$Cache.GetCacheElements() | where-object {[datetime]$_.LastReferenceTime -lt (get-date).adddays(-$mindays)} | foreach { $Cache.DeleteCacheElement($_.CacheElementID) }
Write-EventLog -LogName SCCM_Cleanup -Source "DCM" -EntryType Information -EventId 1011 -Message "Remediation ending for Cleanup CCMCACHE" -ErrorAction SilentlyContinue

The final step is to create your compliance rule.  Set the value to check against to 0 and check the run remediation script checkbox.

Now after you test the new CI assign it to the appropriate baseline(s) for your environment.  Now you can forget about having to manually cleanup the SCCM cache folder ever again.
