Error : "no such object on server"

[K88]

hi,
Windows Small Busness Server 2008, When I try to run CRM under domain admin account a popup comes up saying "there is no such object on the server". I have read various topics about SBS user.Also I can no longer open the CRM Deployment Manager "the selected snap-in did not initialize properly".Any help will be extremely appreciated.

This problem occurs when you try to configure filtering on an Exchange Server 2003 computer that is an administration server that is a member of a Microsoft Exchange 2000 Server organization. The Sender Filtering and Recipient Filtering options cannot be configured in an organization that does not have an Exchange Server 2003 computer as a member.

I think that's where your problem might be, the users were created and then moved, if you create a new user does it still display the problem?Are the original folders in AD still there?

I figured that, but I'm trying to go at it from a 'Grant them only the bare minimum' amount of permissions to do what they need to do to avoid them having access to areas they shouldn't.Will need to go through all the 'Special' permissions to figure out the least I can grant to allow them to create delete contacts & user accts with email addresses as possbile.
I dont want to find out that suddenly these users have control over public folders etc that they didn't used to.
