If some or all of the RAS or RRAS counters are missing in Performance Monitor, one or more of the following conditions probably exist on your Windows NT computer:

1. The Rasctrs.dll is missing or corrupt.

2. The Close, Collect, Library, and/or Open values are missing at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\Performance

To resolve the problem, delete the Rasctrs.dll file and replace it from your latest Service pack. Then use Regedt32 to add any missing registry values at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\Performance

The registry entries should be:

<b>Value name: Close
Data type: REG_SZ
Data: CloseRasPerformanceData

Value name: Collect
Data type: REG_SZ
Data: CollectRasPerformanceData

Value name: Library
Data type: REG_SZ
Data: rasctrs.dll

Value name: Open
Data type: REG_SZ
Data: OpenRasPerformanceData</b>
NOTE: to extract Rasctrs.dll from the RRAS installation file, type:

mpri386.exe /T:<directory path> /C

where <directory path> is the folder you want to put the files in.
