Re: aspnet_regiis.exe -ir -enable destroys perf counters?

re:
-enable

When -enable is specified with -i, -ir or -r, ASP.NET will
be enabled in the IIS security console (IIS 6.0 or later).

You shouldn't run that command on servers running Windows 2000.
Windows 2000 only runs IIS 5.0.

It's only natural that you get corrupted or missing value entries
in servers which don't understand the instructions which "-enable" sends.

Hello everyone,

I hope this is not an FAQ and that somebody can answer this:

As part of our webservice installation we run

aspnet_regiis.exe -ir -enable

on computers where the web service is supposed to be installed. On some computers, notably those
running Windows 2000, we get corrupted or missing value entries in
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ASP.NET_2.0.50727\Performance when running
this command line. Most notably, the DWORD values "First Counter", "Last Counter, "First Help",
"Last Help" are missing and the result is that typically within 1 minute the application event log
is completely filled with entries that look like this:


Event Type: Error
Event Source: Perflib
Event Category: None
Event ID: 1008
Date: 11/10/2005
Time: 1:34:03 PM
User: N/A
Computer: MeinTollerComputer
Description:
The Open Procedure for service "ASP.NET_2.0.50727" in DLL
"C:\WINNT\Microsoft.NET\Framework\v2.0.50727\aspnet _perf.dll" failed.
Performance data for this service will not be available. Status code
returned is data DWORD 0.
Data:
0000: b7 00 07 80 ·..�

When running the command line above, it says something like

"Setup has detected some errors during the operation. For details, please read the setup log file
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\ASPNETSetup_00044.log"

If I look into this log file, the only suspicious line says:

Starting Install common performance counters
2006-11-20 16:56:15 Failure Install common performance counters: InstallGenericPerfCounters failed
with HRESULT 800700b7: 'Cannot create a file when that file already exists. '
2006-11-20 16:56:15

What is going wrong here? I have no idea what "InstallGenericPerfCounters" means, anyone with more
insight into what is happening here? How can we prevent this from happening on our customers'
computers?

Please folks, don't tell me to turn off the performance counters for asp.net, this is not an
option for us.


Any help appreciated,
