I get that message everytime i try to open VPC on an end user's computer.

System Info:
Dell Optiplex GX620
Windows XP SP2
Broadcom NetXtreme 57xx Gigabit Controller

Steps i have taken to try to fix the problem:

Uninstalled / Reinstalled VPC 2004

Verified the "Virtual Machine Network Services" Driver box is checked in my
NIC properties.

Verified that the user account is not under the "Network Configuration
Operators" group.

Manually uninstalled and reinstalled the "Virtual Machine Network Services"
service under my network card.

Updated the Chipset and NIC drivers.


One thing i noticed thats strange, on my pc when i click properties on the
"Virtual Machine Network Services" it has the following information.
Driver Provider : Microsoft
Driver Date: 6/4/2004
Driver Version 2.5.452.0

When i check the properties on the end user's pc, all of that information is
blank.



I have the same model PC as the end user with the same version of windows.
VPC runs fine on my machine.

Any help would be appreciated, this is really frustrating.
