It would use public if there was no gateway defined on the "NIC" that holds the 
address.  If you are able to and haven't already washed your hands of it, what 
happens if you reboot the server with the desired IP and the Windows FW turned 
off?

If it's choosing the public profile and you only have FW rules defined for the 
domain profile, it might be cutting off communications.  If you have FW logging 
enabled for drops you should see those in the pfirewall.log file.

When I am using any other IP, it is properly selecting "domain" profile.  When 
this profile is on, everything is allowed (firewall is wide open).  When using 
the problematic IP, it does not communicate with the domain at all, and I 
assume in that case it is using the "public" profile.

NLA is referring to "Network Location Awareness".  Do you have the Windows 
Firewall enabled, and if so, is it selecting the appropriate profile (domain vs 
private vs public)?  I *think* that might be the domain profile (which should 
be correct), and it might be due to some FW rules you have in place.

No dupe on the other system.  It seems to be OK with it up until a reboot, 
where it has the issue.  All the event log errors I see are related to 
services, et al not being able to talk to the network.

When on a different IP, the only place it shows up in the registry is: 
HKLM\SOFTWARE\Microsoft\windows 
NT\CurrentVersion\NetworkList\Nla\Cache\IntranetAuth\1.1.x.x.x.x - where 
x.x.x.x represent the IP in question.  The values here are "Failures" and 
"Successes".  I did actually try wiping it out before to no avail 
(interestingly, it came back).

The only thing I would know to do like that is kill the adapter and re-add it 
(what I did in the first place), which is what someone else suggested.  I am 
able to workaround the issue by simply using a different IP, and I am OK doing 
that in this instance.  It is worth noting that I did the same process with a 
nearly identical server and had no issue.  I think I must have done something 
in a funky order the first time that caused the problem.

Hm... and you're sure there isn't a dupe out there on another system?  Very odd 
that it would go to an APIPA address, but that should show up in the event logs 
if it thinks it has a conflict.

While you have it on a different IP, if you search via regedit for the desired 
IP, do you find it anywhere?

I'm not familiar with VMWare, but if it were in Hyper-V, I'd maybe try to 
recreate the machine configuration after that, reattaching the vhds.  Is 
something like that an option?

That is the process I followed (shorthanded in my explanation).  There is no 
NIC showing other than the current one.

Run cmd as administrator
set devmgr_show_nonpresent_devices=1
devmgmt.msc
When device manager launches toggle it to show hidden devices again.
Look for NICs that don't belong and remove them.
Reboot

I wanted to upgrade the NIC on a vSphere based virtual server, so I powered 
down and removed the existing NIC and added a new one.  The IP was statically 
assigned.  After rebooting, I got rid of the old NIC (show hidden devices in 
Device Manager, uninstall), and I set the IP of the new NIC to match that of 
the old and reboot.  After doing so, can't log into domain anymore and figure 
out IP is not responding.  After much troubleshooting, I am able to get the 
machine working by changing the IP to something else via netsh (network control 
panel hangs).  That's all working OK, reboot a couple of times, and confirm the 
old NIC is not a phantom.  Change the IP back to the desired one again, and am 
able to ping it.  Reboot, and same problem again (can't login to domain-based 
account, no response from IP).  When I do an IPCONFIG, it shows a self-assigned 
address (169...).  When I do a NETSH INTERFACE IP SHOW CONFIG, it shows my 
desired IP address (although it is not responding).  I try to use netsh to 
change it to that address again and it rejects it (indicating it already 
exists).  I assume the address is hung somewhere, but I can't find any sign of 
it in the registry or anywhere else.  I also tried "netsh int ip reset" and 
"netsh winsock reset" (found while googling) to no avail.

Basically, if I try to make this machine use the old/desired IP address, it 
will not work.  Any other IP (that I have tested) works fine.  It will work 
with the old IP until a reboot.  Any clue what I might do to make this Windows 
2008 R2 Server forget this old IP?

Thanks,
Bill Mayo
