Hi There,
I am auditing a server and have found a weird issue?!?! if that's what it is.
I've never seen this before, but here goes.I've noticed 2 ip addresses on a win2k std server however I can only find information on 1 IP address.
There are 2 nics on the server, 1 is enabled the other disabled. The disabled nic was set for dhcp. The enabled server has a single ip address assigned.
When I run ipconfig /all it shows 2 ip addresses, if I run route print it shows 2 routes, according to ipconfig settings. I can't find the 2nd IP anywhere on the server. I've even gone through the registry and the only indication is a pointer to an internal web address that no longer exists.
I'm not sure what to do as I'd like run ipconfig /flushdns but I don't know if that'll cause any issues.
Has anyone seen this before. In 9 years of IT I've never seen this occur?
I'm not seeing things as I've had another techie look at it.
Your advise would be much appreciated.
Cheers,
Jim
Is it a 169.168.x.x ip number?

No, the current IP address that I can find is 10.21.80.10 and the one I'm trying to find info on is 10.21.80.20.
Any idea's?

I'm not a network specialist, however I use ID Serve program to look up IP addresses. You can get it here GRC's free stuff

Hi There,
Thanks for your reply but this wont be able to tell me which device on a server is utilizing the ip address I'm after.Thanks anyway, anyone out there have more suggestions?
I've already used some software and hardware auditing tools such as sysinfo, siw, hp insight manager, some vb scripts, etc...
Cheers,
Jim

Goofylocks:
Have you checked the IP address range of your DHCP server to see if 10.21.80.20 is in that range? Is there any chance that there might be two active DHCP servers on the network? Have you tried an nslookup on the IP? Can you successfully ping the IP address (from the server, and from other systems on the network)?

On the single nic did you check the alternate ip page to see if this ip is there?

Oh and no vmware or other virtual software running?

Hi all,
I've checked all of these options prior to putting up this question. I've done all and more and I'm really stumped on this.It's really weird. I've pinged, nslookup, checked for secondary IP's on the nic's tcp settings, checked on IIS on the default website, I've used some network intrusion tools and it pings but still I can't find the device that is setting this IP address locally on the server. There's no way the a VMware server(using DHCP) or a DHCP server could provide this IP address considering I'm not using DHCP on any local nics.
So as you can see I've extended all attempts so if anyone has any more advise or attempts, I would be most appreciative.
Regards,
Jim.

if you do a nbtstat -A ipaddress does the server come back a2 the host?
you seem stuck on dhcp. I would ignore that in the troubleshooting if you aren't running a dhcp server.
Are you running any kind of virtualization? For example lets say you have host server x at .25 but you are also running vmware and have another server OS running on vmware. It also will have a ip address but different than the server. So in this case you have a single hardware device with two servers each running on its own ip address.
Could this be happening?

Here's a thought; configure a pc for that mystery ip address and you should get a conflict message with the mac address listed. Track down the mac address

Cool tip wanderer.
Waiting to see what happens with this one.

Today seems like a good day to chew through the restraints.
