Windows 7: Remote Access Connection Manager Problems in Windows 7 Ultimate 64bit

I've been having issues with VPN connections and narrowed it down to two services that are not working properly. A sfc /SCANNOW returns no error.

The first service is the Remote Access Connection Manager (RasMan). It's set to manual and starts and stops from the Services panel without any problem.

The other Service is the Remote Access Auto Connection Manager (RasAuto). That's the one I am having trouble with. It doesn't start and I get an error (See popup attached).

I traced RasAuto in RASAUTO.LOG and noticed a failure with TapiInitialize:

[6652] 09-27 16:17:44:609: TapiInitalize: lineInitializeEx failed (dwErr=0x80000048)
[6652] 09-27 16:17:44:609: AcsInitialize: TapInitialize failed (dwErr=-2147483576)
[6652] 09-27 16:17:54:952: TapiMessageLoopThread: lineShutdown failed (dwErr=-2147483551)
[6652] 09-27 16:17:54:952: TapiShutdown: shutting down

So I traced as well RASTAPI.LOG which corresponds to the RasAuto trace:

[2136] 09-27 16:17:24:027: EnumerateTapiPorts
[2136] 09-27 16:17:34:235: EnumerateTapiPorts: lineInitializeEx Failed

I've done my homework so I just need a push in the right direction. I have WireShark and Portmon.exe. How can I check this TapiInitalize:lineInitializeEx ?

Thanks for any help.

PS: Dependencies such as Telephony, Plug and Play, Remote Procedure Call(RPC) Secure Socket Tunneling Protocol Service are all running.
