WMI Queries in Task Sequences with SCCM

Asked by: ServerSupport

Hey Everyone,

I'm trying to consolidate all my task sequences in SCCM down to just a couple but running into some problems.

I use to have a task sequence for every model PC and for every time zone. Needless to say there were a bunch of TS available when a tech would boot up with a WinPE disc. I've since consolidated that into just 2 TS, one for each time zone our company is in. I know it's not the best way to do it, but I have a WIM image for each model PC, and used a WMI query for the TS to determine which WIM to apply. A screenshot is included below of the Eastern TS. The Nevada TS is pretty much the same.

Now I'm trying to have just 1 task sequence that would install XP on any model PC in any time zone using a WMI query that looks at the IP Subnet. Only problem is that the WMI query that I came up with isn't working, more than likely because I have no knowledge of WMI. Below is a screenshot of the Task Sequence. I'd like it to work as follows.

     The deployment group runs regardless of subnet or model PC except for the "Apply Windows Settings" part. The EST task should
     only run when the workstation is on a subnet of 10.15.30.0, 37.0, 40.0, 80.0, 81.0, 82.0, 83.0 and the PHX task should only run on subnet 36.0.

     The Configuring Operating System EST and Configuring Operating System PHX groups should run the same as the Apply Windows Settings task.

     The Software group just runs regardless.

The screen shots below show the WMI Queries that I'm trying to use. The one based on the model of PC works fine, it's the one based on the subnets that's not working. As soon as it hits the Apply Windows Settings EST the TS fails with error code (0x80041010).

Anyone out there know how to do what I'm looking for or have suggestions on better ways of doing this? Also does anyone have suggestions on how I can better learn WMI for future needs?

Also in case it matters, any PC that boots from the WinPE disc should be consider to not having a prior operating system on it. Whenever I PC needs re-imaged it's deleted out of the SCCM database and is throw into the Unknown Workstations collection which is were all Task Sequences are advertised to.

Thanks a bunch for any help!

Any ideas anyone? I've continued tinkering with this and came up with the following WMI condition for the subnets, but now it gives an exit code of 4112 and fails. When I test it in the ConfigMgr console is works tho, giving out a 1 value since my workstation is on the 10.15.80.0 subnet.


SELECT * FROM Win32_IP4RouteTable WHERE Caption LIKE '%10.15.30.0%' OR Caption Like '%10.15.37.0%' OR Caption Like '%10.15.40.0%' OR Caption Like '%10.15.80.0%' OR Caption Like '%10.15.81.0%' OR Caption Like '%10.15.82.0%' OR Caption Like '%10.15.83.0%'

I would guess that Win32_IPRouteTable is probably not a WMI class in WinPE.  What you are trying to do would be easy if you where using Microsoft Deployment Toolkit :)  

What you could do is to run a script early on in the TS to pull out the Default Gateway from Win32_NetworkAdapterConfiguration and wack that into a TS variable.  The reason you need to use a script is because the DefaultIPGateway value (and IPAddress for that matter) are an array of strings, so you can't query them with a WMI query.

I've attached some Sample code (not tested) that would do something like this.

A better approach with the script would be to do all your network location logic detection in the script, and then set a TimeZone Task Sequence variable inside the script.  Then in your TS all you need to do is put a TS Variable Condition on your Apply Windows Settings.

set objNetworkAdapters = objWMI.ExecQuery("select * from Win32_NetworkAdapterConfiguration where IPEnabled = 1")
For Each objAdapter In objNetworkAdapters
' Get the IP addresses
If not (IsNull(objAdapter.IPAddress)) then
	For each sElement in objAdapter.IPAddress
		If sElement = "0.0.0.0" or Left(sElement, 7) = "169.254" or sElement = "" then
			'not a valid IP address
		Else
			' This must be our IP Address
			sIP = sElement
		End if
	Next
End if
' Get the default gateway values
If not (IsNull(objAdapter.DefaultIPGateway)) then
	For each sElement in objAdapter.DefaultIPGateway
		If sElement <> "" then
			sDefaultGateway = sElement
		End If
	Next
End If
Next  
 
Set oEnv = CreateObject("Microsoft.SMS.TSEnvironment")
oEnv("IPAddress") = sIP
oEnv("DefaultGateway") = sDefaultGateway
