Troubleshooting using RDP

Parent Previous Next

I am using Fax Voip Softphone running on Windows Server 2003 via Remote Desktop Connection. After sending the document to the Fax Soft Virtual Printer, Fax Voip Softphone Create Fax Wizard window does not appear on my screen. I am not able to enter the phone number where to send a fax. Where is the problem?

By default, your RDP client connects to your server using a terminal session. Keep in mind, that Fax Soft Virtual Printer is not designed to work in a terminal window of server operating system. You should connect to your Windows Server 2003 operating system using the console session. The problem should be solved on the client side (on the computer you want to work from). To configure your RDP client to operate in console mode, select Remote Desktop Connection shortcut, in the menu click Properties to open Remote Desktop Connection Properties dialog box. In the Shortcut tab, in the Target field add /admin option to have “%windir%\system32\mstsc.exe /admin”. Note that with some older versions of the RDP client, you should use the /console option instead of the /admin option (see documentation to your client Windows OS). See also in the Connect to remote computer using RDP section of this chapter.

To resolve this problem, as an alternative, you can use Send a Fax using Direct Converting function to create and send the fax. See also Send a Fax from the Fax Panel chapter.

Where is the problem?

Unfortunately, currently there is no solution to this problem for these operating systems. Use the usual way to access the system.

I have many difficulties when I try to operate with Fax Voip Softphone via RDP connection. Where is the problem?

To be honest, the program is not designed to be run through RDP. Install the software on your client computer and use the normal way to run the program.
