The network: Server is running Win2K Server. 9 client workstations, all running WinXP Pro. Static IPs. Running activity directory. D-Link 10/100 16-port switch.
Comcast came in yesterday and installed a Cisco router. Apparently, its a modem/router combo because the coax cable (we have commercial cable service) is connected right to it. The tech assigned the router an IP in our scope (192.168.8.x). When he was done, he came over to me and gave me the gateway address he assigned to the router, and the ISPs primary and alternate DNS server addresses. I made the changes to the network settings on my workstation, and BAM! I had Internet access. Life was grand. I also made the necessary network config changes to 2 other workstations. We were all happy. We shut our computers down for the night.
When we restarted and logged-in this morning, we immediately noticed that it took a very long time to hit the desktop after logging in. After that, we had no access to our mapped network drives, and the computer would lock-up when trying to open up My Computer. One error message I received when trying to open a mapped drive was something about the connection could not be enabled, and to make sure that I had access to the server that authenticated me.(?) This problem only exists on the 3 machines I made the network config changes to
additionally, if I delete the DNS server IP address from each workstation and then restart, I have no network problems at all.
So, Im guessing this has something to do with DNS
I have no idea what, though. One thing perhaps worth noting
we are running Active Directory. The domain name is local, not local.com. When I was setting up Active Directory, it wouldnt accept a domain name with the .com suffix. We do have webpage for which we have a registered domain name, but it is hosted by Valueweb. Additionally, Comcast assigned us a static, public IP
I havent been able to ping that address, and I cant hit it through my Internet Explrorer.
HELP!!!! PLEASE!!!! Any ideas?
