Instead of using @LServer directly, check it and cast it to a var.

Also, don't use vars inside strings.

Code:
If @Lserver <> 'IM'
 $LServer = @LServer
Else
 $LServer = 'the right server at this site'
EndIf
...
use I: $LServer+'\common$$'

Insead of all those separate InGroup() statements that all map to the same place, put them all in one.

If InGroup('cs-office','ws-office','ms-office')
