In my windows 2000 and 2003 environment, there is a problem going on, each
week or month one of the servers renames and takes the name of a server "abc"
which already exists in the network, The issue has been going on I have
enabled auditing and check each time the server has been renamed for event
560 in the security logs for mof\dification to the registry(host name), I am
not able to get a solution so far, can any one help me get to a solution.

PS: There are no network scripts running
All the servers apparentlt take one name "abc"
abc server is a simple windows 2000 running an application and is not a DC
or holding any special previlidges.

The answer is probably in your trailer: ""Old jokers never die.
They just terminate and play silly games." In other words,
look around you and check who is in a position to play
this trick on you. A good starting point might be to change
the password for each and every admin account.
 
I don't think so. I have admin acct passwd to limited people. and any server
that is getting renamed is getting the same new name! I also tried keeping
admin passwd with me only for certain time period but few servers were
renamed during that period too!

Its real puzzling how its all happening?
 
It is a safe assumption that Windows does not change a
computer name by itself. If it did then we would have heard
about it a long time ago.

It follows that this is done by an outside agent. This could
be a hacker, a joker, or a virus/malware program. To isolate
it, you must start collecting evidence. Create the following
batch file c:\windows\ticker.bat

Line1 @echo off
Line2 echo %date% %time:~0,5% %ComputerName% %* >> c:\Logs\Name.log
Line3 regedit /e c:\Logs\name.txt
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerNa
me"
Line4 for /F "tokens=2 delims==" %%a in ('type c:\Logs\name.txt') do echo
%%a >> c:\Logs\Name.log
c:\tools\psloggedon >> c:\Logs\Name.log

Now use the Task Scheduler to schedule two jobs:
1. One job to launch this command each time the server starts:
c:\windows\ticker.bat Server Booting up
2. One job to launch this command once every 10 minutes,
24 hours a day, 7 days a week:
c:\windows\ticker.bat

When the next name change happens, examine the log file
carefully. It will tell you this:
1. When the computer name was changed.
2. When the server was rebooted.
3. When the new name became visible.
4. Who was logged on.
