AD GPO log on script failure

Testing Environment: Virtual Server 2k5 R2 hosted on Win2k3 Ent x64 Ed.
Testing Environment LAN: Local NAT bound to MS loopback adapter with WAN
access via ICS

Virtual OS Instances:

Win2K Server: Virtual AD PDC.
WinXP: Client Machine
WinVista: Client Machine

GPO Log On Script:
Language:VBS.
Purpose: Map Three Network Drives (X,Y,Z)
located on PDC

Problem: When logging onto the WinVista instance with an AD account that is
a member of Either the local Admin Group or local Power Users group (test
account is a member of one or the other never both) the VBS logon script
fails to acctually mount the network shares. I have verified that the script
is running by inserting a couple wscript.echo statements before and after the
wscript.mapnetworkdrive statements, the wscript.echo's come up as expected
but no network drives. If I remove the AD account from the local Admin or
Power Users Group the drives map perfectly upon next log on. If I perform
the exact same test on the XP instance (ie add the testing account to either
Local Admin or Power Users) drives map perfectly in both cases.

Any Ideas

Please update if you find an answer. I am experiencing exactly the same issue.
