I am a newbie, so please bear with me. The company I work for is running an Exchange server. The thing is, it gets IP address conflict problems every few days and doesn't go any further than the login window, and sometimes I can't even VPN into it to use a Remote Desktop connection. Is there something I can change so this stops happening? Thanks!

Does the server have a static ip address?

First you should make sure that your server IP isn't in a DHCP scope. If it is, change the scope or make an exception.

If not, find the system causing the IP conflict. When your server goes down due to IP conflict, take that opportunity to turn off your NIC and ping -a serverIP to get a name. (of course, easier if computer names are based by room or user)

You could get on the DNS server and look at what names are resolved to the IP. If there is a conflict you should be able to see what machines have that ip.

The significant problems we have cannot be solved at the same level of thinking with which we created them.

assuming of course you are running dhcp and have it dynamically updating dns.

Imagine the power if you knew how to internet search

If you want aviod IP Conflict, you can have many ways. First, using nbtstat -A command.. you can find who use your IP address. Second method is install IP conflict protection firewall.. something like IP Holder 1.0(it can found from google). This will be remove your conflict popup message on your SERVER or PC. Also it protect your ip address from other user. If you install it the other user never use your ip address. Thanks..
