I have CRM 4.0 installed with Internet Facing Deployment, so I am accessing
the CRM via the Internet at: http://www.yqcomputer.com/ :5555.
Everything worked fine for a year or so until today, when the external link
is showing me the login screen, but when I type my username/pass it says:
annot connect to Microsoft Dynamics CRM server because we cannot
authenticate your credentials. Check your connection or contact your
administrator for more help. The internal link http://localhost:5555 works fine..
