PostPosted: Team Foundation Server - General, Access TFS thru VPN Top

I'm just a developer and know next to nothing about networking. I do know that our TFS is on our primary domain and the domain is NATed behind the firewall. When I try to connect to the TFS thru VSTS I get this error message.

---------------------------
Microsoft Visual Studio
---------------------------
Microsoft Visual Studio
TF31002: Unable to connect to this Team Foundation Server: server06.
Team Foundation Server Url: http://server06:8080.
Possible reasons for failure include:
- The Team Foundation Server name, port number or protocol is incorrect.
- The Team Foundation Server is offline.
- Password is expired or incorrect.
For further information, contact the Team Foundation Server administrator.

Since I am theTFS admin it's not a very helpful error message.

I don't even know if the VPN is working as it did before we installed the NAT. Before, when I was authenticated I could open Windows Explorer and browse to the network servers. Now, I can see the domain, but when I try to expand it's node I'm getting this error.

<domain> is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

The list of servers for this workgroup is not currently available.

Since I have network admin privileges, permissions is not an issue.

I've been working with the network admin for the past 2 weeks on this and he keeps claiming there is no problem and then sends me a server NAT address, as if I'm trying to get a file off the TFS server. He doesn't understand that a 'server' is more than a collection of files and printers.

In fact, I can't even connect thru VPN to the SQL Servers on the domain anymore. I've about convinced myself this has something to do with the NAT we've installed, but since I don't know anything about it I can't guide the network admin toward a resolution.

If anybody has an idea of where I can go from here, I'd be greatly in your debt.

I normally follow the following troubleshooting steps:-

1) See if you can resolve your TFS instance:

At a command prompt type "nslookup tfsservername"

2) See if you can connect to port 8080 on your TFS instance

At a command prompt type "telnet tfsservername 8080". If you connect hit some random keys and press enter a few times. If you get back a response you can see your TFS server.

My guess is that step 1 is failing for you. The address that your network guy is giving you may be the address you are now supposed to use If neither work then you can tell your network guy that you cannot resolve the address.

Sounds like you have a communication issue somewhere, either on the network or between you and the admin :-)
