Networking Nightmare

by qbert0 . Updated 17 years ago

I’m a newbe to the game. Started trouble shooting a few networks that were ghost riding along for two years (no admin at all)!
Both were set up by a programing novice who quit right after they were up and running.
The one I need help with went down the week before I started working. It has about 15 workstations (static IPs) running vista connected to one 2003 server performing DC, File/Print Share, VPN, and DNS (or at least thats how it was set up). Will be adding more workstations in the future.
I started by replaceing modem and two 24-port switches. Downloaded all updates (days worth). Tried to Multi-home the NICs the way the other network is set up, but nope. Then updated drivers and tried teaming using Broadcom Advanced Control Suite 2, but it would not give me the option (greyed out). Then tried both on auto config and then just disableing one, but the network is still unreachable. Can’t ping any workstations from server, but one teacher workstation can ping server after I changed tcp/ip to auto. Both have internet access. Can’t logon to any other workstations. States “there are currently no logon servers available to service the logon request”. Can’t remote into any either. Teacher’s station can remote into server though. All hardware looks to be in working order.
Maybe has to be something to do with the TCP/IP or DNS settings.

Any help would be great.
