TFS always use integrated credential to connect to TFSServer when joined into the domain?

Here's why: In your first piece of code, you used the following constructor of TfsTeamProjectCollection: public TfsTeamProjectCollection( Uri uri, ICredentialsProvider credentialsProvider ) And the second parameter is defined as: Used to get the credentials when the credentials of the current environment fail So if the credentials of the current environment (aka the limited domain account you mentioned) do not fail, it will use that instead of the Administrator account you created the ICredentialsProvider with. Did you log on as zanewill when you tried this code? The second constructor you used takes the second parameter as the "authentication credentials" so it's the one being used.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
