Question for Run Prorgam remotely

[demei_meng]

psExec \\computer cmd /c mkdir "c:\testVBP"

I'm using the same command on Run Program for machine A and B. Machine A is Windows XP professional and machine B is Windows 2000 server. Machine A has psexec.exe in the system32 and the machine B has the whole PsTool package. The PsExec version on both machines is v1.72. I set "Read program output from" to "None". When I test this step, machine A has the build successfully completed. However, machine B has PxExec started but cmd command never ends and the output window keeps fleshing...

What should I do to fix the problem on machine B?

Thanks,
