After scanning for viruses on our network, we realised that tcp/ip was disable on one of our domain controller. That machine has our dhcp server, exchange server 2003 and our DNS. I was able to re-enabled the tcp/ip but could not get the exchange services running because it was complaining of not able to find the domain. We restarted the other domain controller but that didnt help. we shutdown all servers and start them again and we have the same problem on the domain controller i just fixed the tcp/ip. What is going on?? I need help because our network is down and the whole of yesterday no one worked!!!!!!!! that is how stressful the situation is!!!!!!!!!!!!!!!

Try to add this server to the domain again.

Go to the command prompt and type:

IPconfig /flushdns
Net Stop Netlogon
Net Start Netlogon

Then provide a screen shot of your DNS folders to us. It sounds like your DNS SRV records, (specifically your MSDCS records) are a forward lookup by istelf. This is the default configuration of the first server on the forest.

You will be able to ping the domain name because it is registered on other DNS servers. This DNS server may not have its SRV records registered.

If Domain services have stopped, Then disconnect this server and download Malwarebytes to see if you have the Conflicker virus.

The Conflicker virus can infect client computers and other servers WITHOUT USER INTERACTION. It is important to you to disconnect these from the LAN as soon as possible when services start to fail and stop. You are showing signs of having Conflicker.

Yesterday i was able to get it working. But anytime i restart the server it disables the tcp/ip. i have run the following command and restart then assign the ip again.

netsh int ip reset reset.log
netsh winsock reset.



Why do i always have to do this..

I think I would uninstall TCP/IP and reinstall it.

Otherwise, you might go to the command prompt and type. SFC /scannow.

SFC (system file checker), looks at the computer to determine if you are on the right versions of main OS files. It also checks them for corruption. HAVE YOUR OS DISK HANDY, if you run this utility.
