Communication failure over W2k LAN

[AngelicKnight]

CEO's assistant shares his printer over our W2k network. Up until the other day, no problems. Then, suddenly, it just stops responding for no apparent reason. Checked out the matter, and no one's computer can connect to his printer now, even though it can be seen on the network.

Next, I tried removing his address lease from DHCP to see if restoring it would fix the failure in network communication. Restarted the machine, he got his IP address back, but the address lease has not yet reappeared in DHCP on the domain controller.

Then, I removed him entirely from the domain, restarted, then added him again. Finally, I removed and readded the computer, reinstating print sharing. No luck.

So, any other ideas? 1) How do I get his address lease to reappear in the DHCP window on the domain controller, and 2) how can I get communication to this machine restored?

HI

A few questions
1. Is the communication problem with this machine one way or two way ?

2. What happens if you try to ping the IP of the machine from another machine on the network.

3. Can you ping the loopback address or any other IP from the the assistant's machine.

4. Did you use ipconfig /release then ipconfig /renew to get a new lease for the machine ?

1. One way; it can communicate with the others normally.
2 & 3. Pings are working fine.
4. Yes
