How to repair TCP/IP in Windows 2000 via the System File Checker (SFC):

Important:  you must be logged on as an Administrator to scan protected files AND you may be prompted for your Windows CD.

The ability for shared system files to be changed or overwritten by non-operating system installation programs is a common problem in the history of Windows operating systems.  These changes can result in unpredictable system performance, ranging from application errors to operating system crashes.  This problem affects several types of files―most commonly dynamic link library (.dll) and executable (.exe) files.

Windows 2000 and Windows XP's System File Checker (SFC) scans all protected system files and replaces incorrect versions, if any, with correct Microsoft versions.  This includes TCP/IP files.  There are a variety of SFC commands; however, the following command will work quite well:  SFC /SCANNOW.

To run this command, do the following.

Click Start and select Run from the menu.


The Run dialogue box appears.

In the Open field enter SFC /Command where /Command is one of the commands listed above.


The Windows File Protection window appears.

Be patient.  The scan may take several minutes.
