Clients use Visual Studio 2013 connecting to TFS 2012 on a 2008 server. TFS has been working fine until this morning.
Now all clients get error TF400324: Team Foundation services are not available from server....... Technical information (for administrator): Unable to connect to the remote serverRetry.
On the server I am able to access the TFS Admin Console and everything shows online, etc. Also on the server I am able to access http: // localhost:8081/tfs and view the collections, etc.
I have restarted the IIS site and used iisreset.exe.
I have confirmed 8080 and 8081 ports opened in server firewall.
I do know that clients received Windows updates overnight.
Suggestions on other things to look for / try greatly appreciated.
