[ADSM-L] SV: [ADSM-L] 50Mb restored in 4.18h....

I actually restored the files to my workstation, and the network settings are
fine
Duplex mismatch does not cause the speed to go down to modem-speed from 1995....

your network sucks? (to put it mildly :) ) I'd check to see if there is any
mismatch in duplex settings anywhere. Remember, auto-negotiation on the host,
and a fixed 100 full-duplex setting on the switch will lead to a host at
half-duplex and tons of collisions.
