Problem:

When installing an agent on a machine using the Discovery Wizard in Microsoft's System Center Operations Manager (SCOM) problems may occur due to network settings.

One such error is:

The MOM Server failed to open service control manager on computer machinename.domainname.

Therefore, the MOM Server cannot complete configuration of agent on the computer.

Operation: Agent Install

Install account: SCOM_server

Error Code: 800706BA

Error Description: The RPC server is unavailable.

Resolution:

The first step is to ensure that the system running the Discovery Wizard can ping the target system using the fully qualified machine name, i.e. machinename.domainname.  If it cannot then the network settings on the client should be checked.

On the target system for the agent go to the Advanced TCP/IP Settings, DNS tab of the appropriate connection and ensure that the domain name is entered correctly in the to the "DNS suffix for this connection" field and check "Register this connection's address in DNS" and also "Use this connection's DNS suffix in DNS registration".  Then ipconfig /flushdns and ipconfig /registerdns on the client system and ipconfig /flushdns on the SCOM system.
