SBS 2003 Fax Server access not available over VPN
Posted on 2006-05-07
I have configured the Windows SBS 2003 fax server and it operates normal on the LAN. When connected via VPN I can print to network printers on the LAN but the Fax Wizard information erors out that it is not available. I can't help but think that this is a firewall issue.
What I have done in an attempt to correct the problem so far is:
1) Opened Ports: MS Fax Services 135 TCP, 445 TCP, Net Bios print spooler 139 TCP
2) Modified permissions on C:\D&S\All Users\App data\MS\Windows NT\MS Fax * (Per previous posting suggestion on EE) *
I have actually added the Server Fax and other printers when connected via VPN, but simply cannot fax in that manner.
I have however been doing this work on a machine that is not a member of the domain, so I am not sure if that would have any affect on the process.
Any advice is greatly appreciated.
