Hi folks, 3cx up to date on windows 2008 using IIS, works great. I install Sharepoint on server. management website now needs authentication. (regardless what I supply it doesn't let me in). I enabled 'windows authentication' on mangement website. Still no go. backup, deinstall, reinstall 3cx, restore -- phone system still works. Website still needs authentication. Any ideas anyone? I don't want to spin up yet another virtual just for 3cx. Thanks in advance. Cheers Dean, Dean.
