You deploy System Center Operations Manager 2007 at your company. All computers are joined to the corporate Active Directory domain. All client computers in the Active Directory domain run Microsoft Windows XP. You attempt to perform a client push installation of Operations Manager agents to several client computers. The installation fails on some of the computers.
You receive the following error message: The RPC server is unavailable. You need to install agents on all client computers. What should you do?
A.
Disable the Windows firewall on the computers that exhibit the failure. Retry the client push installation of the agent.
B.
Enable the Computer Browser service on the computers that exhibit the failure. Retry the client push installation of the agent.
C.
Add the Management Server Action account to the Domain Admins Active Directory global group. Retry the client push installation of the agent.
D.
Add the Management Server Action account to the local Administrators group on the computers that exhibit the failure. Retry the client push installation of the agent.
Explanation:
A: CORRECT
Before you will be able to install the client using the Computer and Device Management Wizard, make sure that all the required ports are opened between the server and the client. The management server responsible for deploying the client has to have both the Server Message Block (SMB) port, which is TCP/UDP port 445, and the Remote Procedure Call (RPC) port, TCP port 135, opened on the server as well as the client. If either system does not have these ports available, the deployment will fail. On top of that, if there is a firewall in between the systems, the deployment will probably fail due to requirements with the RPC port range. Most administrators will not open all the ports that can possibly be used by RPC, so a manual installation will be required in that case
