Today I was installing Team Foundation Server 2008 on a Windows Server 2008 server where I installed WSS 3.0 SP2 when I realized I was going to get error connecting to an existing Windows SharePoint Services server.  The error is TF220037: The Windows SharePoint Services administration site could not be found at the following location:  http://myserver:17012

Basically this error means that it can’t find the WSS Central Administration site.  Usually when I see this error it means that the WSS Central Administration site is installed on a different port.  The easiest way I have found to get the correct port number is to open the Central Administration site and look at the port in the URL.   In my example below the correct port is 21810.  I simply updated the port on the installation screen on the left and it worked fine.

To open Central Administration,  go to Start > Administrative Tools > Central Administration.

That’s it! I hope it helps.
