2.8.1 Using the Ungermann-Bass XNS Transport Stack If you are using the Ungermann-Bass XNS transport stack and running Windows in 386 enhanced mode, you must make sure the transport stack is not using expanded memory. If your system is configured to provide expanded memory with a memory manager such as EMM386, you can disable that product's expanded-memory option. Or, if you want to continue using expanded memory, you can disable its use by the Ungermann-Bass transport stack as follows: 1. Open your PROTOCOL.INI file by using a text editor such as Windows Notepad. PROTOCOL.INI is located in your LAN Manager directory. 2. Find the section [XNS_XIF]. If you're using Notepad, you can find this section by choosing Find from the Search menu, typing [XNS_XIF], and then choosing the OK button. 3. Add a line NOEMM, or, if the line already exists, make sure that it is not commented out with a semicolon (;) at the beginning of the line. 4. Save your PROTOCOL.INI file. 5. Restart your workstation. .
