RWW stopped working

Hi

SBS 2011.

I installed Visual Studio 2012 on the server and now I cannot RWW from outside to the server. I can RWW and Remote Desktop to server internally just fine. I have run all wizards under Network in SBS console but no luck. What can I do from here to fix the external RWW?

Thanks

Regards

Update: I noticed IIS Express 8 was installed as part of VS2012 installation. I uninstalled it and re-ran all wizards under Console->Network but no luck.

Update 2: Running BPA gives below warning. I did the suggested resolution but no luck?

Category: Configuration

Source: 432

Issue: The certificate for the Remote Desktop Gateway service seems to be bound incorrectly.

Impact: If the certificate for the Remote Desktop Gateway service is not configured correctly, users cannot connect to Remote Web Workplace.

Resolution: At an administrator-level command prompt, type
REG ADD HKLM\SYSTEM\CurrentControlSet\services\HTTP\Parameters\SslBindingInfo\0.0.0.0:443  /v DefaultFlags /t REG_DWORD /d 1 /f
net stop tsgateway
net start tsgateway
