I have posted a similar possible problem with ingroup under
Local Ingroup Issue
I'm not sure whether the two are related but its possible.

Site B has a script that maps drives dependant on group membership.
This was working fine as far as I know until the weekend when the groups were renamed to fit with a new naming convention.
The code is as follows
Code:
If Ingroup ("G CHWHT_Chris_Team")
Use O: /delete /persistent
Use O: "\\mha1\Clients\!Chris's Client List"
If @ERROR
		$rc = WriteLine (1, "@DAY-@MDAYNO @MONTH," + "@TIME," + "@USERID," + " has problems mapping the O drive," +"\\@WKSTA\C$" + @CRLF)
		report
	EndIf
EndIf


This is an example of one group but the problem seems to be happening for any of the drives which are dependant on the ingroup function.

Now for some users the drive isn't mapping even though they belong to the group concerned, however for some they are. For the one's that aren't no errors are reported.
I have tried using ifmember.exe /list from a cmd prompt and this shows that the user is a memeber of the correct group with the new naming convention.
Any ideas?
