OWA/website/vpn/remote access unreachable externally

My client has been experiencing issues with her external sites.  Currently, OWA, Web, Remote Web Workplace, and VPN are unavailable externally.  The error is listed below.

Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)

All of the ISA rules appear to be allowing access to the proper hosts and sites.  I checked the certificate authority, and the ONLY certificate that appeared to be having issues was the web cert.  All others were operating fine.  After I reissued the web cert, it came up fine.  However, the sites are still unavailable externally.

The most odd thing about this is that the client states that this loss of services happened over a period of time, and happened with multiple employees before it happened to her.

Any suggestions about where I should look?  Thanks in advance!

I would verify that the user is using HTTPS and not HTTP in their URL.

user is using http.  However, the site does not work on either protocol.

I've tried option 1 in the first comment, with no success.  I have not explored the second option.

I guess what is so puzzling is that this (according to the client) fell off in stages.  First, one of her employees was unable to work.  Then another, and finally her over a period of weeks.  I would tend to think it would be an all or nothing principle whether it was certificate failure or permissions.

I'll have another opportunity to address it tonight.

Another update:

Per microsoft, I've re-run the SBS wizard "Connect to the Internet" (against my better logic).  It did have the positive result of allowing external access to the main website.  However, the remote access web and exchange are still showing the permissions issue.

Issue resolved

Resolved issue by running the wizard above, then modifying the rules from an internal site to the external facing site.  Placed the web rules at the top and disabled other rules that were not relevant.  Sites are fixed now and the client can get in.  Thanks again to all that posted.
