For a server that is running Microsoft Exchange Server 2007, you try to load the MSExchangeIS performance counters remotely. The performance counters do not load, and you receive the following results:
This issue occurs because the MSExchangeIS Performance Counter library (Mdbperf.dll) does not load its performance counters. These performance counters must be used in the security context of the remote caller. In this case, the remote caller does not have permission to register "MSExchangeIS" as an event log source within the Application log. The MSExchangeIS event log source is created to support the logging of performance counter failures. The failure to register the event log source causes the MSExchangeIS Performance Counter library not to load, and this omits the MSExchangeIS performance counters from the list of available performance counters.
By default, only members of the Administrators group, system accounts, service accounts, and the interactive user (NT AUTHORITY\INTERACTIVE) accounts are granted permissions to register an event log source that is used to write to the event log. Be aware that this permission is not granted to BUILTIN\Users accounts.
To work around this issue, you have to grant the BUILTIN\Performance Monitor Users group (S-1-5-32-558) permissions to Write to the Application log on the Exchange 2007 server. Then, you must use the BUILTIN\Performance Monitor Users group to grant remote access to the performance counters. To do this, follow these steps.
