The following troubleshooting steps can be used to diagnose the problem. You should perform these steps on the Management Server that your were connected to when the User Interface was running the Discovery Wizard and attempting to remotely install the agent.
Perform an nslookup on the target computer name. If not IP address is returned, try using a different DNS server.
Example of nslookup using the target computer name from the command line: nslookup [ComputerName]
Example of nslookup using a different DNS server: nslookup [ComputerName] [DNSServer]
nslookup dc1.contoso.local dns1.contoso.local
If the above doesn't result in an IP Address, you may need to change the DNS configuration on the Management Server to ensure it can resolve the IP Address of the computer you are attempting to install the agent to.
