AD computer object is missing suddenly, why?
This is using mixed Windows 2003 and 2008 AD Domain. There are 1 W2K3 and 2 W2K8 DCs. However, a computer object of one of the newly-created file server that created 2 months ago was found missing. It can't be find in AD Users and computers MMC of any of the 3 DCs. But, if i type "net view" in any PC, I managed to see the filesvr, and I still able to browse to any file shares on the server.
I did tried to dis-join this fileserver from the domain, reboot, and then re-join it back to the domain without problem. However, still can't find the computer object in the AD, why? What is went wrong with the server? How can I get back the computer object?
Thanks.

enumerate all computers in the AD, it likely was moved to a sub OU..
dsquery computer | find /i "computer name"
depending on how many you have, it might be that it was attached to a differently named object.
Try this, use the system you can not find to access another systems admin share that is commonly not used as a fileserver with a share, then see how this system is reflected on that system's share accessing interface (compmgmt.msc sharing/fileserver role.)

you can not control the logon server, it is determined by a dns query on the local server locating available DCs using a srv record lookup.
Your best bet is to identify and resolve the issues causing the replication issues.

On the problem DC you could demote it... Make sure AD is clear of all metadata then pro-mot the server again

Eventually, I demoted the DC because this DC having ad replications failure with other 2 DCs. Thanks for Arnold's explanation and pointed the correct culprit.
