It sort of depends what the switch is configured to. If the switch only supports auto-neg, manually setting the nic will cause problems as well. I would say make sure all network elements agree on the duplex setting. Besides, if its a duplex mismatch, it should show up on the machine's netstat -ni output. ---Mike >Sascha Holzleiter wrote: > >>Hi, >> >>I just installed a new system with 5.2.1 which shall serve as a NFS >>server.
