Hi,

We have seen two issues causing this to happen.
First, we have seen this with switched hubs or switches. The switch needs to be recycled and
if the issue happens again, then it may need to be replaced. You can check that by putting two
machines on a dumb hub and see if the issue still exists.
Second we have seen this caused by firewall services installed on the machines (could be
part of the antivirus package that has things like "server protect" etc.). This specifically has
been seen with AT&T software.

Look into these items and you should find the sloution to the error you are seeing. Remember
you can always place two machines on a separate dumb hub for testing.

Hope this helps,
Gary
