Getting Started

If you want to use Windows networking features such as connecting drives and printers, or use the PC-NFS Windows applications, you must:

1.	Start the PC-NFS network before starting Windows.

2.	Start the TSR rtm.exe before starting Windows

If you have not started the PC-NFS network and the RTM, when you enter Windows, you will receive an error message indicating what is not started. If you will be running for a long  time without the network running, you may choose to turn the Network Warning off. See Network Warning for details.

The PC-NFS applications also require the PC-NFS network and the RTM to be run before they can be used.

When you start Windows, your current user name (login name) is in effect. If you wish to login with a different user name while in Windows, you can do so through the Network Icon in the Control Panel, or by using the Login Application.

To run the Console Messaging Application

If you plan to run the Console Message application you must also start the TSR listener.exe before starting Windows.

If you want to be able to receive messages immediately, you should start the Console Messaging application from the PC-NFS Group. Messages that are received by your PC will not be displayed unless this application is running. You may have this application started automatically when Windows is started. To do so, start Console Message, and choose the Options menu. Select Startup. Windows will automatically start Console messaging when Windows is started. You can also move the Console Messing application into the Windows Startup Group.

To start RTM or listener

If you receive a message that you need the RTM or listener to run:

1.	Exit Windows.

2.	Type rtm or listener at the DOS prompt, and press Enter.

The TSR will load, and you can restart Windows.

Note: You can not start TSR's from a DOS box in Windows.

Norton Desktop Compatibility

If you are using Norton Desktop, you should configure the PC-NFS software as described in Configuring PC-NFS and Norton Desktop.

Printing to Local and Remote Printers

If you want to print both to a printer attached to your machine, and a printer on the network, you must make sure that Control Panel and Print Manager are correctly configured. See Printing to Local and Remote Printers for more information.

Configuring PC-NFS and Norton Desktop
Configuring PC-NFS software and Norton Desktop

Norton Desktop interacts with the network differently than Windows applications such as File Manager.

Note: Read the README.TXT file supplied by Norton Desktop for recommendations about using the Norton Desktop with networks. It contains important information about how Norton Desktop interacts with network drives.

To ensure compatibility with Norton Desktop and PC-NFS Software

To run PC-NFS software with Norton Desktop 1.0 you must edit the PCNFS.INI file, and may have to edit the AUTOEXEC.BAT. You may also want to change the default Norton Desktop display configuration.

1.	In your PC's Windows directory, modify the PCNFS.INI file to specify a value of 1 (true) for the Norton 1.0 compatibility, as follows:

[Compatibility]

Norton1.0=1

2. 	If you are running Norton's Erase Protect Utility, modify your AUTOEXEC.BAT file to ensure the lines:

 EP /ON

IMAGE

are after the lines:

 	NET INIT

 	RTM (this line is optional)

3. 	If you have performed step 2, reboot your PC so that these changes take effect. Otherwise, you can just restart Windows.

Seeing Network Options and All Network Drives

When you start Norton Desktop, you may not see any options related to connecting and disconnecting drives in the desktop area.  Be sure that the Full Menus option is enabled, by:

1.	Within Norton Desktop, choose the Configure Menu

2.	Choose the Full Menus option. Once you have done this you can Connect to Network Drives and Disconnect Network Drives just as you do in File Manager.

In Norton Desktop you may not see network drives that you mounted before starting Windows. To see these drives:

1.	Choose the Configure Menu.

2.	Choose the Select Drive Icons option.

3.	In the dialog box that appears, choose All Network Drives to see your network drives.


Serial Number

Each copy of PC-NFS software has a unique serial number, which is sometimes called a license.

To see the serial number for your copy of PC-NFS software

1.	Choose the Network Icon from the Control Panel.

The serial number for your copy of PC-NFS software is displayed on the Network Icon dialog box, along with other information about the PC-NFS network.
