Unknown device on the network

After a power outage, one of the servers cannot be connected to

Server is "acquiring network address" even though it is hard-coded (192.168.0.10)

Server reports IP  address conflict

nbtstat reports that IP resolves to something named RTKDASHOOB (not the server's name)

MAC of RTKDASHOOB changes frequently- and always to something that doesn't show up when I enter it into an online database

Cannot open UNC or HTTP of the IP nor connect via Computer Management

If the network cable is pulled from the server, ping to the IP or name fails

Malware Scan of server comes up clean

Install second NIC- no change

Hard code second NIC to 192.168.0.12

Can now connect to the server by name, and if I ping it, it resolves to .10 even though there is no cable in the NIC that is .10

If I try to connect to the server by IP it fails, even if after I create a host file entry

Thoughts?

It could simply be a defective network cable?

Alt : disable/remove first nic settings and set second nic up as .10

I tried swapping cables with another server that was running fine.  
Did the second suggestion as well- the "new" NIC does the same thing as the onboard one.

try these command from a elevated cmd prompt ( run as administrator)
netsh int ip reset c:\resetlog.txt and netsh winsock reset catalog after rebooting go into networking and reconfigure your static ip information

Ran the reset- no change (that was two days ago, sorry for the slow reply).  The ghost .10 was still present at the end of the day.  Had everyone reboot their PCs that night and yesterday morning it was gone and has not come back.

This one will likely go into the "never did figure it out" file.

Thanks for the attempts though.  I'll close this out.
