System Center DPM 2012 R2 Install Error ID: 812

Error id 812 is indicate that you have a problem with SQL Server Reporting Services

This is very clear and also its too clear that you forgot to configure SSRS

MSSQL installation do not auto configure SSRS

DPM also failed with default SSRS configuration because DPM use https to connect SSRS and default SSRS configuration work with http

Also another complexity is you have to create/generate self signed certificate

To create self signed certificate i advise you download selfssl why because automatically you can create and import it to trusted container of your server

Use such command in cli and pls pls do not care about error message what it out

Selfssl.exe /N:CN=MACHINENAME /V:365 /T

Also more important one is if your server in domain pls use FQDN for create self signed certificate otherwise you will see that you can not call reporting server url

And pls recreate reporting db  after you introduce and configure self signed certificate because otherwise you will get some can’t encrypt messaged from SSRS

After all you will install DPM lovely 🙂

Bye
