I am receiving the following error when trying to access our SharePoint 3 site while connected to an external network via IE or FF using https://intranet.domain.com
501 Not Implemented. The requested method is not implemented by this server.
We are hosting the site internally with IIS 6 on a win2k3 R2 server.
SharePoint works fine internally with the URL above, we recently implemented SSL and it is working fine with a self signed cert for testing. External access has never worked, before SSL was implemented the page would timeout and a 401 would be returned to the browser. Now that SSL is implemented we are prompted to accept the Cert, then we receive the 501.
Any suggestions would be greatly appreciated!
