Jetstress will not load performance counters after applying a service pack or hotfix

There is another issue that Database Performance counters can be broken for Exchange after using JetstressUI.

In certain cases when Exchange Server was installed before Jetstress, uninstalling Jetstress could result in unstable Database Performance counters. To restore access to Database Counters after Jetstress has been removed, do the following:

At a command prompt, change the directory to the Exchange installation directory (exchsrvr\bin).

1. Run the command unlodctr ESE to ensure that the Database Performance counter registration information has been completely removed from the registry.

2. Run the command lodctr esperf.ini, which should correctly register the Database counters.

3. The Database Performance counters will be available the next time that you start System Monitor.

    Hi hmlee,

    When I started JetStress, it failed to open because the "error:cannot read instance JetStressIU" similar to your article titled.
    I hit <Fix Errors> button. It shows fixed. Hit <Continue> button, it failed again.

    Then I found your article and followed your instructions for intent to fix it. And it came out another issue as follows:

    1. Ran LODCTR ESPERF.INI and it responded:
    "Unable to find initialization file esperf.ini"
    Found that there is no ESPERF.INI available in the "Program FilesExchsrvrbin" folder.

    2. Ran search and I found that MSESPERF.INI exists instead.
    Ran LODCTR MSESPERF.INI and it responded:
    "Counters for MS Exchange ES are already installed"

    3. At this moment, I reopen JetStress again. It shown same error. Luckily, this time after hit button <Fix Errors> and <Continue>, the JetStress is ready.

    I am confused. Any idea what is going on? Thanks.

    There are four ese and eseperf libraries:

    C:Program FilesExchsrvrbin>dir /b ese*.*
    ese.dll
    eseperf.dll
    eseperf.hxx
    eseperf.ini

    Please, copy these files to the JetStress installation directory and run JetStressUI again.

    Oh, cool. Thanks. According to your instruction, I found that they all there. I will re-run the JetStress and will let you know the outcome.

    Thanks again. You have a great weekend.

    Hi hmlee,

    It works nicely as expected. Thanks a lot for getting the appropriate fix for this.
