HP-UX Unix to WinNT

This looks like the 100BT card in the NT box has a Full Duplex/Half Duplex 
setup problem.

We have seen this at our site loads of times now with 100BT connections. Some 
network card/OS combinations fail to negotiate the correct Duplex setting. If 
there is a mismatch between the switch and the server you get *VERY VERY* slow 
network traffic.

You may need to turn off the automatic duplex setection and force it. You will 
be best off forcing Full Duplex at the switch and the NT server.

Hope this helps.
