Keep ADSM Server Service running.
Try to stop, remove and then re-install the Schedule service without the option /validate (or /validate=yes). This will force ADSM to validate its password with the one that is in the Windows Registry:

>>ReadPswdFrom Registry(): ReadOpenPathEx(): win32 RC=2
>>sessOpen: Error 137 from signon authentication.

The Schedule service can be started again.

This worked with me !

Dr. Watson error pops up for DSMCSVC.exe. I look in the error log and I see
the following messages:

     Has anyone seen this problem before ?
