  2. Right-click the network interface you want to disable, and then click Disable.
  3. Right-click the network interface again, and then click Enable.

Verify

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify TCP/IP connectivity:

  1. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Click Continue when prompted by User Account Control, and then provide the administrator password, if requested.
  3. Type ping followed by an IP address of another host on the network.
