This time a team member tried to access the DPM Console and received the following message:
Verify that the DPM service is running on this computer.
there were no problems with the DPM Service and i was able to log in through the console.
the cause for this problem may be :
a- He is not a local admin on DPM machine (this not the cause here because he is a domain admin).
b- He not have permissions on the SQL Database. (This Was the Cause)
Now close the Management studio and try.
