This is usually a permissions problem. Use the TFSAdmin Tool to check permissions on the SSRS and Sharepoint systems (which are separate from TFS itself, unfortunately). Check that the settings are working the way you intend by browsing directly to the Reporting website & the Team Project Portal from inside IE.
There are other possibilities, however.
- Check the Application event log on the server to see if your attempts to connect generate any exceptions.
- If you're using SQL Server 2008, make sure you have Team Explorer fully patched up to 2008 SP1. (you'll need to re-run SP1 if you installed Team Explorer afterward)
- Make sure you're connecting to TFS using the same URI as other people. If you're using a fully-qualified domain and they aren't (or vice versa) you could be exposing a server configuration problem in TFS's Registration database. Details here: http://blogs.msdn.com/buckh/archive/2007/03/31/configuring-team-foundation-server-to-use-fully-qualified-domain-names.aspx Also, there is a known bug in the admin util: http://support.microsoft.com/default.aspx/kb/959126
- Check, recheck, and re-recheck your proxy settings. Both software configuration (TFS inherits them from IE / Control Panel) and at the network level (whether you're on some LAN segment that gets proxied differently). Use an HTTP protocol analyzer on a good & bad machine to be certain.
