I was trying this command in my network. It worked for both w2k and Nt4 -> Both
machines shutdown properly ( using net rpc shutdown ). However, when I tried to
abort the shutdown -> only the NT 4 machine aborted it. The w2k machine
continued with the shutdown sequence, and it didn't abort.

Here is the debug = 4 output for both

NT 4 ( abortshutdown )
