Failed to resolve IP address

Microsoft.SystemCenter.AgentManager.IPAddressResolutionFailed.Monitor (UnitMonitor)

Monitor for "push" agent install failing because of IP address resolution failure.

Knowledge Base article:

Summary

Remotely installing the agent failed due to IP Address resolution failure.

Causes

While performing a remote agent installation, the Management Server attempts to resolve the name supplied by the IP Address that we directly connect to. If this fails, the Name Resolution service used on the network might not be working.

Resolutions

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]

nslookup dc1.contoso.local

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.

For more information on troubleshooting agent installation, see Troubleshooting Issues When You Use the Discovery Wizard to Install an Agent(http://go.microsoft.com/fwlink/?LinkId=181932).
