I had a working fax server in a production environment that had been working for years. On Tuesday users were unable to send faxes. Faxes still were being received and placed in a folder.
When looking at the Fax Account it showed Disconnected. After removing that and trying to reconnect, I got a message saying that I did not have security permissions.
I tried it from the fax server itself. It works. I tried it from the workstation using a Domain Admin account that we use and it works. I temporarily made the user a domain admin logged out and logged back in. Still cannot connect to fax server.
Other things that I have done.
uninstalled/reinstalled modem on server
Removed Fax Server Role and re-added
Took ownership of Fax in the Advanced Security section by domain users
Removed fax on server from workstation and re-added successfully
Re-added permissions in the fax manager for domain users, network service, everyone
Disabled Windows Firewall on server
Disabled Antivirus on server
