I have installed ZCM 10.3 on a new SLES 10 SP3 server. I wanted to start a Server Inventory Scan. If I start that I get an error :

Could not find a Handler associated with the following type: Inventory.ScanNow.

And then a second error :

The handler [NULL] was not found.

If I run ZDC it looks fine. What could be the problem of this ?
