VM client restart

I am using a wyse terminal (thin client) with xpe. I have disabled explorer in registry and replaced the shell with the vm client so at startup it looks like a windows logon but its VM view client instead. This all works well however when I log off it just goes to a blank desktop (because there is no explorer). Is there a way to get the vm view client to load straignt into the logon screen once the previous session logs off?

Use a batch file as the shell:

vm.bat

:START

{vmclient.exe} (use whatever the real filename is)

goto START

That way it keeps restarting after it is terminated.
