We are having the same problem with a couple of our connections.  The PCs
are running NT and once in a while they just lose it--their connection is
very slow and then they have trouble reconnecting.

I took them off of our DHCP server and gave them a permanent IP address
and it 'seems' to have fixed the problem-so far.  It been several weeks
and all if well.  See if that helps.  If you find another solution, please
let me know.
