Windows 2008 R2 Fax Server (Ongoing issue)

Question

I have a Windows 2008 R2 active directory, fax services work inbound through USB modem - have 50 Windows 7 clients connecting to the fax server and outbound faxing works.  Here's the issue:  After a few days, the clients start getting server disconnected
on the fax clients.  When I go to the Server, I restart the fax services, even though no event viewer shows any error's.  I do see inbound fax errors of some not received, but these are not consistent when this happens.
I restart the fax services (by restarting print spooler service), and clients still show disconnected.  If I remove the account from the Windows 7 Fax client and try to add it back - I get the "You do not have security permissions to complete this
operation. Contact your fax administrator for more information".
Now, I reboot the windows 2008 R2 server and fax services work again inbound and outbound, and I can reconnect the Windows 7 Fax client that I previously removed.  UAC is turned off, Domain Admins full control to Fax server permission, and domain users
have fax permissions.
This issue has happened over the last 3 weeks, I've uninstalled Fax roles, and reinstalled many times prior and followed the fax setup step by step on techarticles - like I stated, the fax services work then stop, and rebooting the server allows the faxing
to work again.  This server does house Exchange 2010 SP3, but the only thing effected or having issues on this box is Fax services.  Any suggestions to look?

Hi ITQ_Jhays,
Please go to Control Panel -> Printers and share the fax printer.
A similar discussion is for your reference:
I can't connect to fax server from client computers.
If there is anything else regarding this issue, please feel free to post back.
