What happened to cause these network errors?

Added a new switch and tidied up by moving some connections to the new switch and re-arranging others.

Suddenly email server wasn't delivering to the Novell server anymore, users couldn't see certain folders or drive mappings.

Powered everything down then brought everything up again starting with switches, then servers, then workstations and everything ok.

Are switches that susceptible to moving the connections around?

I've seen this happen with an unmanaged Netgear switch where the forwarding table in the switch doesn't seem to relearn a MAC address when it appears on a different port, even though the device that has moved is transmitting into the new port.

Cycling the power on the switch means it has to relearn its forwarding table and everything starts talking again.

Netgear unmanaged switches suck. The managed switches (at least the fsm

700 series) are OK (just OK, not great, but can't beat the price!) and do not have this issue. Haven't tried any of the "smart switches" yet, since they don't do SNMP and I like to use MRTG to watch traffic on the ports.

Spot on - it was an unmanaged Netgear. Thanks for that info.
