If you ran cleanspl.exe and said delete the Standard port monitor, that
would explain this. Here are the steps to get it back. This requires
editing the registry or importing the key from another machine.
the three system files you need should still exist in \windows\system32 (
tcpmon.dll, tcpmib.dll, and tcpmonui.dll ) you can edit your registry entry
and add the monitor back. If the files do not exist copy them from another
installation or expand them from the installation CD.
If you have any Win2k or greater system handy you can export the Standard
TCP/IP Port key and import to the other machine. Even if you do not
export this key if you can look at this key for guidance when adding back
the entry it is helpful.
