<sound of hollow laughter> This is a bone of network contention (no pun intended), particularly with Cisco networks. It is *not* a TSM problem. (As usual, TSM is the World's Best IT Infrastructure Problem Finder.) There are any number of whitepapers, Cisco and otherwise, that insist that all NICs in all networks have speed and duplex settings hardset to the best speed suited to the network hardware. The problem with autonegotiate is that, unless *every* network device in the chain is set to autonegotiate, the entire chain runs at 10/half. -- Mark Stapleton ([EMAIL PROTECTED]) ------------------------------------------------------------------------------ Electronic Privacy Notice.
