JSI Tip 9121. When you attempt to open the Windows Firewall on Windows XP SP2, you receive Error 10047?

When you attempt to open the Windows Firewall, you receive an error similar to:

WINDOWSSystem32svchost.exe -k netsvcs Error 10047

When you run net helpmsg 10047, it displays:

An address incompatible with the requested protocol was used.

On possible reason for this error is an buggy LSP (Layered Service Provider ), a mechanism that can extend the Winsock network socket facility for application.

NOTE: A LSP can provide internet parental controls, Web content filtering, and other useful functions.

To workaround this behavior:

1. Open a CMD.EXE window.

2. Type netsh winsock show catalog>FileName_Before.txt and press Enter to record the LSPs to a FileName_Before.txt file.

3. Type netsh winsock reset and press Enter.

4. Shutdown and restart your computer.

5. Type netsh winsock show catalog>FileName_After.txt and press Enter to record the LSPs to a FileName_After.txt file.

NOTE: The netsh winsock reset command is useful if a malformed LSP results in loss of connectivity, BUT any previously installed LSPs will have to be re-installed.
