Re: IP address already in use

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi Javan,

You should be able to see something like this in your event log (at least on
the server)...

The system detected an address conflict for IP address 10.10.10.10 with the
system having network hardware address 00:0D:9D:93:E9:3B. Network operations
on this system may be disrupted as a result.

This "01:1D:9D:93:E9:3A" is a MAC address of the computer / device that is
causing the IP conflict. If you can locate this device by MAC address you
will know who/what is causing you the problems.

I hope this helps.

I have started getting the "IP address already in use" error. I started
getting this after I brought down our old NT server and brought up a new
2k3 server. The server is the system that is getting this error from time
to time. The DHCP is a Sonicwall with the servers mac address set to a
static IP address in the DHCP. The problem doesnt seem to be causing any
issues yet but something isnt right.

I am also started getting this at my house after I hooked up a linksys
wireless router. I secured the wireless with WEP encryption. It isnt
unusual for me to come home after work and have 5+ of these dialog boxes
to go through. I leave that computer on 24x7.

Any possible causes? Both of these cases are completely different but I
have not seen this problem since I moved to DHCP years ago. Seems wierd
that two of these instances pop up in two completely seperate networks.

Thanks

Jon
