Resolve

Rename the local computer

Computers must have unique names on the network.

To rename the local computer:

You must be logged on as an administrator or belong to the Administrators group to complete these steps.

  1. Click Start, click Control Panel, click System, and then click Change Settings.
  2. Click Change Computer Name, type the new computer name, and then click OK.

 

Verify

To verify that the name can be resolved, ping a remote host by name:

  1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator
  2. Type ping [hostname].
  3. If the ping succeeds, then the name was successfully resolved.

Note:  Ping will fail if the remote server does not have File and Print sharing enabled and a File and Printer Sharing exception in Windows Firewall enabled. On Windows Server 2008, installing the File Server or Domain Controller roles will do this, as will sharing a printer.
