Hi I am installing TFS and following are the environment's configuration on which I am installing TFS Active Directory Server :- 2003 Server Data Server :- which is also 2003 Server, on this I am installing TFS TFS Service Account doesn't have administrator privilege When we are installing TFS 2008 with domain account on another server then Error No :- 28002 is generating at last stage of installation for Share point. I tried to search defination for above error. I got defination which is "Require fully qualified name" like :- XXX@domain.com . I have one doubt is it possible AD and TFS on same machine.
