[OpenAFS] Problem with large data transfer (WinNT AFS, please HELP!)

[Neulinger, Nathan]

Do regular afs accesses work properly on the machine? i.e. is it just
when you try to do this large copy when things break?

If it is always broke, then are you messing around with any personal
firewall packages such as blackice or similar?
