I am working on a Windows 2000 Network that has 3 windows 2000 servers and 20 windows 2000 workstations. The servers 1, 2, and 3 are not all communicating. Server 1 can not communicate to servers 2 and 3. Servers 2 and 3 can communicate with each other. Both DNS and WINS are running on server 1. On server 1 itself is listed as the primary DNS and primary WINS. On server 2 and 3 the IP address of server 1 is listed for the primary DNS and primary WINS. You can ping all servers from all other servers. I have verified the above settings. I have verified the server service is running. I am not sure what the next step should be. The OS is fully patched.
Other symptoms to this problem is that some of the workstations appear to login and authenticate to server 1 and some to server 2 or 3. This is noted becuase some users can log in and gain access to the resources on server 1 and some can gain access to the resources on server 2 and 3. This seems to be machine based not user based. I have checked the workstation to make sure the host file does not have entries relevant to this network. The host file does contain two entries that helps a software program Reflections connect to a remote system accross a point to point connection to another company. Things to note: 1. If servers 2 and 3 are shutdown and you attempt to login you get a message that their is no domain controller. 2. If server 1 is shutdown and you try to login you get a message that the computer account is invalid. 3. If all 3 servers are running then the computers seem to split themselves between 1 and 2 & 3.
I have not been able to find a pattern to this problem except that it seems to center around the communication between the servers.
These are no good news. Looks like the old server no 4 was the PDC emulator and it was removed without transfering it's role to another server.
Go to server 1 and force it to be pdc emulator. Run ntdsutil.

We recently endured a series of broadcast storms that caused our ISP to shut us down for brief periods of time. After going through a multitude of tests, we determined that the issue was related to Intel NIC drivers on some new HP desktop computers …
