For no apparent reason OWA has stopped working on one of my clients servers. It's a single 2008 SBS Server and when I logged on to it today I can't get OWA working either internally or from the outside world just get "Internet Explorer cannot display the webpage" error. IIS is running and there are no exclamation marks next to SBS Web Applications. Have checked the web publishing log and got the following message:
The World Wide Web Publishing Service (WWW Service) did not register the URL prefix https://*:443/
for site 1. The necessary network binding may already be in use. The site has been disabled. The data field contains the error number.
Would really appreciate some diagnostic steps as it's causing the company huge issues.
Many thanks for your help
