Remove and add TCP/IP protocol or reset Winsock catalog
The TCP/IP protocol is not properly installed on the network interface.
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.
To remove the protocol from the network interface and add it again:
- Click Control Panel, double-click Network and Sharing Center, and then click Manage network connections.
- Right-click the network interface you want to repair, click Properties, clear the Internet Protocol Version 4 (TCP/IPv4) check box, and then click OK.
- Right-click the same network interface, click Properties, select the Internet Protocol Version 4 (TCP/IPv4) check box, and then click OK.
If the problem persists, reset the Winsock catalog:
- Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
- Click Continue when prompted by User Account Control, and then provide the administrator password, if requested.
- At the command prompt, type netsh winsock reset, and then press ENTER.
- The output of the netsh winsock reset command should indicate a successful reset.
- Restart the computer to complete the reset of the Winsock catalog.
To verify that an IP address is assigned:
- At the DHCP-enabled client computer, click Start, click Run, and then type cmd.
- Type ipconfig /all to view lease-status information.
- The output of the ipconfig command should show an IPv4 or IPv6 address marked “preferred.”
