Active Directoy / Exchange

I ran dcdiag, couldn't find anything wrong.

Yet in my exchange box, I got those error
1-
Windows cannot load the extensible counter DLL MSExchangeIS. The first four bytes (DWORD) of the Data section contains the Windows error code.

2-
Performance counter updating error. Counter name is Time in Resource per second, category name is MSExchange Activity Context Resources. Optional code: 2. Exception: The exception thrown is : System.InvalidOperationException: Instance 'ad-microsoft.exchange.store.worker-microsoft.exchange.store.worker.exe' already exists with a lifetime of Process.  It cannot be recreated or reused until it has been removed or until the process using it has exited.

Last worker process info : System.ArgumentException: Process with an Id of 9780 is not running.

I tried lodctr /r did not help
I tried winmgmt / resync
also did not help

I don't seem to have errors in gym AD yet when I browse a user properties I get many S1-6)373737 that are "list" GUID.

I wonder why and how come there are no tools (even 3rd party) that do the checks and balances to make sure that ur infrastructure is running correctly without error..
