It's been over 38 hours now, so I created an issue in the Tracker (TW-6741)

Any update on this?  I need to get this issue resolved before the end of next week.

I followed your directions but didn't find a log file where I had specified the temp folder.  I then wrote the output of the console to the log file.  The error is included in that log file; the full stack trace is there.  I made some minor changes to the log file to omit the url, user id, and directory structure.

Thanks for your help.

I double-checked the URL with a project that is currently working in TeamCity and they match.

Then I tried to go to the http site of the tfs server path manually.  When I try do so through Internet Explorer, it gives me a message "Error: Access Denied".

Does TeamCity need access through this web interface?  If so, why are the other 20 or so configurations working against that same server?

OK, the problem was that I wasn't including the port.  The latest problem is with the results file:
