If you've ever tried to discovering a computer using our Discovery Wizard and the results were not what you expected (the computer failed to be discovered)... here are some great steps to get you started.
Fix: Add the computer to Active Directory. Make sure the DNSHostname property is set correctly for the computer; this property can be viewed on the “General” tab of the computer’s property dialog in the “Active Directory Users and Computers” management console.
If the machine does not respond to a ping request or fails a remote agent install with "RPC Service Unavailable", the Windows Firewall is turned on. Turn off the firewall or set exceptions to allow for "File and Printer Sharing" and, optionally, ICMP Echo.
If the NetBIOS and FQDN names do not match, then the DNS records for the machine must be corrected.
If the agent installs but, fails to contact the OpgMgr Server, connect via Terminal Services or Remote Desktop to the agent computer and use the ping and nbtstat commands to verify that the agent can resolve the NetBIOS and FQDN names of the OpsMgr server that will manage it.
Through Group or Local Policy, grant the OpsMgr server action account the permission to access this computer from the network. By default, members of the local Administrators and Power Users groups should have this permission.
If the failure occurs during agent install, add the OpsMgr server action account to the local Administrators group. If this is not possible due to security policy restrictions then:
1. Reject the pending install from the "Pending Management" view.
2. Run the discovery wizard again
3. On the "Administrator Account" step select "Other" and provide an account (domain or local) that has administrator privilege on the computer
4. If the account is a local account or does not have rights to access Active Directory then check the box to use the MOM server action account for the discovery task
5. Discover the computer and push an agent to it.
