Web Access Module can only work with TeamFoundationApplication - what's the problem?

Question

I installed tfs2012 the other day and played around with the web access tool. Now when i try to get to the same app I get an error as described in the title. http://{server}:8080/tfs.

The event log entry has been posted below. The only thing to note is right now I have assigned a domain admin account as the service account for all tfs services. The account details have been replaced with placeholders below.

Hi Naeem,

Thanks for your post.

Do you know which detailed operation caused this issue?

Please launch your TFS Admin Console>>Application Tier, in the right panel, click Refresh, everything work fine? If yes, type http://servername:8080/tfs in IE to open the Web Access, still can’t open it correctly?

What’s the Service Account in Application Tier panel?

On Server machine, click Start and select Run… to open the dialog box, and input iisreset.exe and click OK, wait it run completely. Then try to reopen your Web Access again.

Everything looks fine under Application Tier in the admin console.

This error occurs when I attempt to open the Web Access page.

The service account is tha same as the one in the event log entry i posted earlier. Don't really want to share it here for security reasons.

Tried an IIS restart and a server restarttoo, still no luck.

Please look at the Global.asax file in your <install-location>\Microsoft Team Foundation Server 11.0\Application Tier\Web Services directory.  It should look like this:

<%@ Application Inherits="Microsoft.TeamFoundation.Framework.Server.TeamFoundationApplication" %>

What do you have in yours?

Hi Naeem,

Thanks for your reply.

It seems that your Global.asax file disappear in that location. Please try to repair your TFS 2012 Server, then check if can resolve this issue.

Answer 6

How do you suggest I repair it? The installer has no repair option.

Neither is there a repair option when I go to Programs and Features through the control panel.

Answer 7

Hi Naeem, 

Sorry for that.

You are right, there’s no the Repair option in Control Panel>>Uninstall program for TFS 2012.

You can try to add the Global.asax file under Web Service directory manually, as Ed said, the content in Global.asax file is:

<%@ Application Inherits="Microsoft.TeamFoundation.Framework.Server.TeamFoundationApplication" %>
