Hi, We a trialing team Foundation Server, and I run a set of Windows Updates on the server this morning. Team Foundation now inoperable (???). Event log state:- A failure was encountered while launching the process serving application pool 'TFS AppPool'. The application pool has been disabled. And unable to browse to either through VS.NET or Team Foundation Web Access, getting error 503, service unavailable. Questions:- What particulare set of updates would reconfigure source-control? (and why? and how to reverse?). Thank you.
