I am working with a new installation of TFS2012 and after working within a project collection for a bit I went into the Admin Console to change the group membership. Clicking on the Group Membership or Administer Security links within the Admin Console results in an error:
The request was rejected by the server. HTTP code 400: Bad Request
I've verified and reapplied both the service account permissions and the Admin Console Users permissions with no luck. I can, however, configure the security via the web based control panel for the collection.
Anyone have ideas of the possible cause?
apparently TFS is real pick on which IIS bindings are configured. By reverting to the default "*" bindings instead of a specific host header I was able to get all the security buttons to work.
Now I have two bindings for the tfs website in iis.
1st: *:8080 2nd: tfs.company.com:8080
