what vedor is your switch and gig cards? we have windows with gig cards which
do get set to auto (intel cards), they dont do full duplex as 10/100 cards do
it. some sun gig cards we can set to 1000/full.

case there is no choice. This is a windows environment and I am seeing the
same thing - but interesting that this started happening when upgrading from
3.4.1 to 4.5 - has anyone seen this?
I am at my wits end and dont know how to solve. Veritas does have some ways
of testing network without NBU involved to show that it is not NBU but then
what do I tell the network guys?
Thanks for the dialougue, this is mostly helpful.
