JSI Tip 6910. How do I re-install TCP/IP in Windows Server 2003?

If you examine the the Properties of the Local Area Connection and select Internet Protocol (TCP/IP), the Uninstall button is dimmed, because TCP/IP is a core component of Windows Server 2003 and cannot be removed.

Microsoft provides the Netsh.exe tool to configure and monitor Windows Server 2003 networking.

If you issue the reset command in the Internet Protocol (IP) context, it will rewrite the HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpipParameters and HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesDHCPParameters keys, just as if you had removed and re-installed the TCP/IP protocol.

The reset command to 're-install' the TCP/IP protocol is:

netsh int ip reset logfile.txt

where:

NOTE: You can issue the command from a CMD.EXE prompt or batch file.

NOTE: If logfile.txt exists, the data will be appended to the existing file.

NOTE: If the registry keys have NOT been altered, the log file may be empty. The log file content is dependent upon the configuration of your computer.

NOTE: To view help for the netsh command, the following are valid:

          netsh ?          netsh int ?          netsh int ip ?          netsh int ip reset ?

The following log file is an example from running the netsh int ip reset logfile.txt command:
