Following the repair steps suggested in the More Information link does not resolve the problem.

To resolve this error, please use the steps below to make proper configuration changes which will then allow DPM reports to be e-mailed.

NOTE: Some steps may not be necessary if you encounter the problem after an upgrade from DPM 2012 SP1. Review and perform the steps as applicable.

1. On the DPM 2012 R2 server, create a new local group called "DPMDBReaders$<DPMServerName>" In my example the DPMServername is WINB-DPM.

Figure 2.

2. Create a new local user called "DPMR$<DPMServerName> and provide a strong password that never expires. See figure 3 below.

Figure 3.

3. Add the newly created user to the DPMDBReaders$DPMservername group that was created in step 1 above. See figure 4.

Figure 4.

4. Start SQL Management Studio using administrative privileges and connect to the SQL instance used by DPM. UnderSecurity, right-click on the Logins and select New login… then browse to add the local group DPMDBReaders$<DPMServerName >. Once the group is added it will be listed as seen in figure 5.

8. Right-click the DPMDBReaders$<DPMServerName>" group and select Properties. Under the Securables section, click onSearch. On the add objects dialog, click OK. On the Select Objects dialog, click the Objects type, then check the stored procedure checkbox. Browse and add the following two stored procedures:

Prc_MOM_Heartbeat_Get

prc_MOM_ProductionServer_Get

Grant the Execute permission for both of the stored procedures added. See figure 9.
