Routing and Remote Access Service - Error 3604

I'm trying to set up a VPN through my wireless router
(Netgear MR814v2) but when I try "Allow Incoming
Connections" in the new connection wizard, I get the
error: "Incoming Connections depend on the Routing and
Remote Access service which was unable to start. For more
information, check the system event log."

Which I did:



The Routing and Remote Access service terminated with
service-specific error 3604 (0xE14).

I swear, it worked not but just a few days ago. I have the
three services it depends on started just fine (Telephony,
Remote Access Connection Manager and Remote Access Auto
Connection Manager).

Searched on Google and Microsoft for a few hours and found
nothing. Tried some diagnostic commands:

sc query remoteaccess

SERVICE_NAME: remoteaccess
TYPE : 20 WIN32_SHARE_PROCESS
STATE : 1 STOPPED

(NOT_STOPPABLE,NOT_PAUSABLE,IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 1066 (0x42a)
SERVICE_EXIT_CODE : 3604 (0xe14)
CHECKPOINT : 0x0
WAIT_HINT : 0x0

Same error code, 3604. Apparently Microsoft doesn't have a
list of the codes and what they mean for each service, or
have hidden it well enough to where I am unable to find
it. I recently installed SP1, which is probably to blame.
After several tries to get it working I installed the SP2
beta, which didn't help. I'm hoping I don't have to
reinstall everything, because I just built this computer
and this install is barely two weeks old.

I would appreciate it very much if anyone could tell me
what was going on... thanks.
