SBS 2008 Fax Server Disabled

Hi, this one was a rather annoying problem, as it seemed to be a client issue but it was not. I struggled to find clues on the internet, and none helped me. Since i solved it on my own I'd like to share... you can never know.

Symptoms:

• Clients cannot send faxes with Archive media error. You change the archiviation folder in client settings, but nothing happens.
  
• The fax server doesn't send or receive anything. Looking at the properties you find that all activities are disabled (general tab). If you try to remove the disable flags you receive an "Unexpected error".
  
• In the event viewer you find an "Access Denied" error related to the archiviation folder.
  You try to change the archiviation folder on the server, but the Browse button is greyed out. If you run the Fax Management Console with elevated privileges you can browse the folders, but whatever folder you choose you receive an Access Denied error.
  

Solution:

As a matter of fact the Fax service cannot get access ti the archive folder or to the configuration data, so it becomes disabled. I don't know why it worked before but in order to make it work again I had to change the Connection properties of the Fax service from Network Account to Local System Account. After restarting the service i got access to the archive folder and could reactivate services.

hope this helps
