Perflib error in event viewer - Callmanager

I m getting this error on my publisher (4.1.3sr3b) every few seconds. Any thoughts on how to fix this ?

The Open Procedure for service "DHCPServer" in DLL "C:\WINNT\system32\perfctrs.dll" failed. Performance data for this service will not be available. Status code returned is data DWORD 0.

Re: Perflib error in event viewer - Callmanager

Looks like your receiving performance lib errors, which means the

performance counters for DHCP are not installed correctly.

Try the following:

Exit to a command prompt

cd \winnt\system32

unlodctr c:\winnt\system32\dhcpctrs.ini

lodctr c:\winnt\system32\dhcpctrs.ini

please rate helpful posts.

I always seem to get this error when building CCM's.

If the instructions above does not help you, you can fix this by removing the DHCP/perfmon key in the registry and then reboot your server.

Let me know if you need more details.

Re: Perflib error in event viewer - Callmanager

Tried the above commands.

Still get the same error.

Thanks.

Re: Perflib error in event viewer - Callmanager

understand that the CM server is reporting the following error in the

Application log:

Event Type: Error

Event Source: Perflib

Event Category: None

Event ID: 1008

Description: The Open Procedure for service "DHCPServer" in DLL

"C:\WINNT\system32\perfctrs.dll" failed. Performance data for this service

will not be available. Status code returned is data DWORD 0.

The above is a known issue in Microsoft Windows which is covered by the

following MS article:

How To Fully Uninstall a Performance Monitor Extension

http://support.microsoft.com/default.aspx?scid=kb;en-us;247226

<>

:http://support.microsoft.com/default.aspx?scid=kb;en-us;247226>

Per the above document, you need to remove the open value from:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP server\performance

by following the steps below:

To completely remove a performance monitor extension, first identify the

service name of the product that supported the custom counters. In this case

"DHCP server".

Use RegEdt32.exe to traverse to the following subkey:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCP server

Select the "Performance" subkey and from the Edit menu, click Delete. This

action deletes the Performance subkey and all its values.

Please make a backup of the registry before modifying it. You should reboot

the CM server after modifying the registry for the change to take effect.
