I have installed Visual Studio on the Windows slave and can access TFS with Visual Studio as well as the tf executable on the server. I have added the following path environment variable on the Windows slave.

"C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE" and shutdown and restarted Hudson.

The problem is with running with the TFS plugin in Hudson and supplying all the credentials in the job configuration Hudson cannot connect to the TFS server.

I also tried including the full path in the tf command line executable variable. In the test job, the first command the plugin generates is

"[tfs-emd-test] $ "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\tf.exe" workspaces -format:brief -server:http://tfs.**********.com:8080/tfs/tfs01 ********"

I get the error message "Unable to connect to the remote server" and then "FATAL: Executable returned an unexpected result code [100]".

I have also tried creating a cmd file with all the tf commands embedded, however this also fails with error message "Unable to connect to the remote server"
