Question : After Windows update, NIC has limited or no connectivity

Last night two computers did windows update. (These are XP Machines). They now cannot get an IP address. There is a third computer on the network, which did not do the updates last night because it was turned off, and it is fine.

What could the problem be?

Answer : After Windows update, NIC has limited or no connectivity

The solution was to add these 3 missing lines to system.conf

fxoks=1-24
fxoks=25-48
fxoks=49-72

I feel dumb now since those are basic/required settings that I always configure in zaptel.conf and should have known that they needed to be in system.conf.
