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.
- Click Start, click Control Panel, click System, and then click Change Settings.
- 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:
- Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
- Type ping [hostname].
- 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.
