I’ve been happily using Team Foundation Server with Visual Studio 2010 for the last couple of months at my current place of work when it has suddenly stopped working. I get the following errors:

Error

enter image description here

If I browse to the wiki (Sharepoint) on the TFS server it works fine in Firefox but in Internet Explorer it fails with:

No authority could be contacted for authentication.

I’m not aware of any changes to the server or my machine that would cause the errors and other users of TFS are not affected.

The TFS server is on a different domain to my machine, but usually I get prompted to login and using a domain prefixed username works. At the moment, I don’t even get a login prompt anymore.

How do I fix this?

    We used a workaround to get past this problem. We configured an entry in the Windows Stored User Names and Passwords tool for the domain of the TFS server. It got around the problem of TFS not prompting for credentials by explicitly supplying them via this tool.

    Stored User Names and Passwords
    Add an entry

    When you change your password for that domain account, you must also change the password here otherwise your account can be locked after failing authentication too many times.
