I have Pastel V11 set up as follows.

Server - XP machine registered and working properly.
Workstation - XP machine registered and working properly.
Problem Workstation - New Win7 machine replacing XP machine that was registered and working properly.

I installed Pastel on the new machine and have done the following.
1. Set up shares to the folders on the XP server (Pastel11 and Pastel11/Custom/Registration)
2. Set PartnerV11.exe to run as Administrator
3. Enabled Linked Connections by creating a DWORD named EnableLinkedConnections with a value of 1 in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Policies\System

When I try to register the Workstation, I get the following message.
"The Server registration has been tampered with and cannot be added"

Any help would be greatly appreciated
