Working at a customer this week I had to implement a service map within SCSM based on a Distibuted Application created with SCOM 2007. This did not work at first! For some reason the objects would not sync. I checked the allow list in SCSM and added all the DA classes that are not in the list by default. Still no succes, the Service map remained empty after sync.

So after some time trying to figure out what was going wrong I discovered that when you configure the connector you first need to deselect all management packs and press OK. So you actually configure it back to not synchronize anytime. Then go back into the connector, hit the refresh button and now select all management packs and press OK again. For some reason, after this procedure the connector started syncing, This step has to be done everytime you add new managment packs to the connector!

Synchronizing started working for me now and my service map was filled with the correct objects. I tested this behaviour in my demo environment and the problem was the same. I checked this with SCSM 2010 SP1 and CU 3 installed. I cannot tell if this problem also exists in other versions of the product.
