Team Foundation services are not available from server - The remote name could not be resolved
This is a client, server or infrastructure related problem on network level. The DNS entry for your TFS server cannot be resolved correctly at times for host dfz-vm223.
Suggestions for troubleshooting:
- On some developer systems, replace the hostname dfz-vm223 by the ip-address of the TFS server. If the problem stop occuring there the DNS system is instable.
- Setup a continuous ping stream (ping -t dfz-vmm223 from command window) and see if the host system is pingable in case you have TFS server problems.
Just found out what the problem was: the problem is proxy related. When we disable our proxy, the problem is gone. It appears our proxy and TFS are troublesome together. If anyone experiences the same problem and you are working with a proxy server, I would suggest you try disabling the proxy too.
I had the same problem, although I'm using VS2012 and a WAN connection to TFS.
I solved the problem by flushing the DNS cache.
To flush the DNS cache, start a command prompt with admin rights: ipconfig /flushdns
You need to do this in all the computers where the problem occurs.
