Microsoft Windows 2000 Server Networking Trouble after configuring Routing and Remote Access.
Posted on 2007-11-21
The setup is this: W2k server....6 clients....in a true server/client domain network. The W2k server is also the Domain Controller. I'm coming behind another Network Admin who designed and implemented with zero documentation.
After adding a NAT rule in Routing and Remote Access on the W2K Server the entire network was non-functional. Server has two NICs and acts as a gateway for the network using NAT and IP routing on the server. All the clients connect to a Switch (not router) that connects to the server's 1st NIC. The 2nd NIC in the server connects to the internet via a DSL modem.
After many hours of reading and tinkering (dangerous I know) I finally got some network functionality back...Routing and Remote Acess (RRA) IP routing seemed to get P2P behavior back between PC's on the network...but the clients still couldnt' get to the web. Turning on RRA NAT returned internet access for all the clients (Server never lost internet access).
My problem is now... the network is rather slow and sluggish...and there seem to be some privilege issues. One client cannot connect to another, where it used to etc...I will elaborate when I'm back on site soon (within 2 hours).
Thanks for any general and specific advice on what I can do to restore things as close as they were to before...and to generally diagnose and speed up a W2K domain.
