PPTP ports in SBS 2003 are missing in RRAS

I was curious if anyone has seen this happen before. I have seen it happen a couple times on two different servers, but it has fixed itself in the past. Basically, in RRAS, the PPTP ports are now missing. We use PPTP for a VPN, but with no ports, we can’t dial in. I re-installed the WAN Miniport PPTP in device manager using devcon.exe, but the ports are still missing. Any ideas? Here is most promising link I found, but solution didn’t working: http://www.chicagotech.net/netforums/viewtopic.php?p=988&sid=1822c315e66f8426bd0160d994ee7523
