About 40 were manually created and the rest were AD synchronized.
OK. So let me recap
1. You manually created 40 resources in the ERP
2. You synchronized an AD Group to the ERP which included the 40
resources for a total of 400 resources/users.
3. You created a new AD Group that included users from the first 400
resources/users for a total of 600 resources/users.
4. When you synchronize the new AD Group to the ERP you receive the
following error:
"This key is already associated with an element of this collection."
If this is correct, then I believe that the problem lies with changing
the AD Group from the old group to the new group. Try the following:
1. Add the new AD group as a member to the old AD group. (This is called
a nested group and it assumes that your AD Domain function is Windows
2000 native or Windows Server 2003) Note
2. Use the old AD group name to synchronize to the ERP.
3. Check the Event Viewer on Project Server and the Domain Controller
for any irregularities.
Let know what happens...
