Obtain current SMS site assignment and compare to “auto” discovered ‘ site

I had a scenario where some of our SCCM clients would fail to communicate to our Primary Servers. Upon investigation it was found that changing the sitecode of the client would resolve the issue at hand, however doing this on a couple of 100 clients would be time consuming.

Instead of logging into each client and clicking on the “Find Site” button, I decided to put Powershell to work and do the work for me. So basically the Powershell script reads a list of computers from a text file and performs the following tasks against each active client:

1. Ping the client to check if it is online
2. If the client is online, it validates if a vbscript exists in the specified location on the client, if not
3. The vbscript is copied to the selected location on the client and executed and writes the information to a log file

Powershell Code:

$FileExists = Test-Path $WantFile

add-content “C:\Temp\SCCM_Sitecode\sitecode.log” “$LogTime ,$Computer, script copy completed.”

}
else {

add-content “C:\Temp\SCCM_Sitecode\sitecode.log” “$LogTime ,$Computer, is offline.”

}
}
