Fixing Lost PerfCounters in .NET
Here is a question I recently answered on the MS .NET Framework Newsgroup:
"Can anyone tell me how to restore the ".NET CLR Networking" - performance counters in my system?"
Open a command prompt and navigate to:
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\ (for v1.1 framework)
C:\WINDOWS\Microsoft.NET\Framework\v1.0.3705\ (for v1.0 framework)
This will attempt to reload the .NET Networking perf counters.
Note: you can also use this to reload any other perfcounters via different INI files in that folder.
