Q: I have an error about the path when connecting to a batch machine.
A: Check your userlogin.bat file. There may be a reference to Visual Studio(VS) in userlogin.bat, but VS is not on batch nodes. Change syntax to "call setup_visualc.bat" or call a different setup file as appropriate.
Q: Can I telnet to batch machines?
A: No. You need to use a remote desktop connection from a login node to login interactively to a machine on which you have a job running.
