'param incorrect' error trying to create custom perf category

[Ben]

hi,

i have this line in a web app to create a custom perf category:

PerformanceCoun terCategory.Cre ate(categoryNam e, categoryDesc,
PerformanceCoun terCategoryType .SingleInstance , ccdc);


....it works ok from another web server, but on a particular one it
gives this exception:

System.Componen tModel.Win32Exc eption: The parameter is incorrect
at System.Diagnost ics.Performance CounterLib.Regi sterFiles(Strin g
arg0, Boolean unregister)
at System.Diagnost ics.Performance CounterLib.Regi sterCategory(St ring
categoryName, PerformanceCoun terCategoryType categoryType, String
categoryHelp, CounterCreation DataCollection creationData)
at System.Diagnost ics.Performance CounterCategory .Create(String
categoryName, String categoryHelp, PerformanceCoun terCategoryType
categoryType, CounterCreation DataCollection counterData)


if i try to run the same code on a c# win app on this same server, it
works... just doesn't work from a web app (the app is running under
an administrator user).

anyone encounter this?

thanks!

thanks!

so just creating a new app pool (with same identity and other
settings) helped resolve the issue....very odd.
