Hello TSMers, I have scoured the TSM Knowledge Base at http://www.tivoli.com/asktivoli on the subject error and found the APAR. However the work around does not work for us. First, the local fix using the unlodctr doesn't work because it is not called "TSM Client Performance", but "ADSM Client Performance". Then, the "lodctr perfctr.ini" command doesn't work because TSM Client Performance is hard-coded into the perfctr.ini file when it needs to say ADSM Client Performance. However, even when you make these modifications, it still does not get rid of the error messages. As for the changes to the registry, the registry key they mention doesn't exist. Any other options?
