Hi Expert , We are getting frequently below Event Error message in the DFS Server : The Microsoft Operations Manager Scheduler Data Source Module failed to initialize because some "hour in the day" could not be parsed on the HH:mm format. Hour in the day: 20 One or more workflows were affected by this. Workflow name: Microsoft_Windows_2003_DFS_Link_Monitor Instance name: toolkitede$ Instance ID: {9CA358E4-C7F7-3595-40E3-9DFF8E6CDFC3} Management group: MOM For more information, see Help and Support Center at Any suggetion & Help will be appreciable. Regards, Sushil

Hi, It looks like misconfigured rule\monitor (Microsoft_Windows_2003_DFS_Link_Monitor). It passes "hour in the day" equal 20 insted of 20:00. Is it custom rule\monitor or it from some vendormanagement pack?http://OpsMgr.ru/

Hi, Please check the settings or overrides of the related monitor. If you found the parameter “20”, please modify it and see if the error persists. Hope this helps. Thanks.

Hi Nicholas, Thanks for the Response .... I modified the parameter to 20 and 50 , but still have same issue and right now I changed to default parameter 0.08. This issue is still active in our SCOM Environment. Any solution and resolution will be appreciable. Thanks, Sushil

Hi, What is the exact error currently, are there any changes? I suspect the “20” might correspond to “hour in the day” and it may be not proper to set it to 50, please set it to a number lower than 20; or set it as the format “HH:mm” and see how it works. Please also check if there are any parameter should be set to the format “HH:mm”, if so, please also modify it. Thanks.
