2 Diff. computers coming up with same IP on network

[metsfan421]

For some reason 2 differently named computers on the network are coming up with the same IP address when pinged from the command line. Any ideas on why this might be?

Check your DNS and DHCP records. Change them if necessary
Also check and see if the IP addresses are statically assigned.

How would I go about changing the DNS and DHCP records?

 

[quell]

From the server- Click on start>programs>administrative tools>DNS or DHCP
Go through and make sure the correct IP and pc name point to the correct workstation.
Usually though one of the workstations should be getting an pop up saying something to the effect of an ipconflict. Are your workstations set up for DHCP or static?

Don't change them, just look for the duplicate record in the DNS.

Do a PING -a <ipaddress> and you will know which one really does have that IP. Then go into the DNS and sort by IP's, you'll see two names holding the same IP. Delete the one that did NOT answer to the ping.

If you have more than one, your DCHP and DNS may not be configured properly and are not removing the DNS entries with the DHCP lease expires.

We are running DHCP. The other tech in my office said that it's probably a problem with WINS. Could that be a factor as well?

It's possible you have a STATIC entry in your WINS that will have an IP with a different name and it doesn't exist anymore... You will need to adjust the record for it to reflect your current server.

You didn't mention anything about removing or adding servers lately.
