RESOLUTION
Check NetBIOS Name Resolution
Check NetBIOS name resolution and network connectivity first by
typing the following command at a command prompt
where
computername is the computer to
which you are trying to connect with Performance Monitor.
Issue this
command over the network and at the target computer. If the command works
successfully and you see a list of the shared resources on the server, try the
following method.
Check Registry Permissions
WARNING: If you use Registry Editor incorrectly, you may cause serious
problems that may require you to reinstall your operating system. Microsoft
cannot guarantee that you can solve problems that result from using Registry
Editor incorrectly. Use Registry Editor at your own
risk.
Start Registry Editor (Regedt32.exe) and check
the permissions on the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurePipeServers\Winreg
Administrators should have full control by default.

Check or Replace Files
- In the %SystemRoot%\System32 folder, rename the
Perfc009.dat file to Perfc009.old. Rename the Perfh009.dat file to
Perfh009.old.
- Copy the Perfc009.da_ and Perfh009.da_ files from the
Windows NT 4.0 CD-ROM to the %SystemRoot%\System32 folder on the local
computer.
- At a command prompt, type the following lines in the
%SystemRoot%\System32 folder, pressing ENTER after each line:
Expand.exe Perfc009.da_ Perfc009.dat
Expand.exe Perfh009.da_ Perfh009.dat
NOTE: If replacing the Perfc009.dat file corrects the problem, you
must reinstall your counters for any program that you have installed previously
and want to monitor. Alternately, if you have a known good backup of this file
you may be able to restore functionality by restoring the backup copy avoiding
having to reinstall all of your counters.
