Troubleshooting Tips and Techniques

1. Clean boot your computer by removing terminate-and-stay-resident (TSR) programs, and third party utilities from your CONFIG.SYS and AUTOEXEC.BAT configuration files. Remove or minimize the use of memory managers. Add back functionality until you discover the utility or combination of utilities that is creating undesirable effects.



2. Verify that the client PROTCOL.INI and LANMAN.INI files reflect your configuration. For more information:
   
   
   • See the Microsoft LAN Manager Installation and Configuration Guide, Chapter 10.
   
   
   
   • See the Microsoft LAN Manager Administrator's Reference Guide, Appendix B.
   
   
   
   • Type NET HELP at the MS-DOS command prompt.
   
   
   
   • Check the on-line help available in SETUP.EXE. Use the F1 key to get clarification on a specific option.
   
   
   
   • Query in the Microsoft Knowledge Base for the name of your specific network interface card (NIC).
   
   
   



3. Force Microsoft LAN Manager for MS-DOS to recreate the hidden DHCP configuration file (DHCP.PRM):
   
   
   1. Use the ATTRIB command to remove the hidden and read-only file attributes.
   
   
   
   2. Delete the file.
   
   
   
   3. Quit and restart Microsoft LAN Manager for MS-DOS to allow the file to be recreated.
   
   
   
   The client automatically creates the DHCP.PRM (a hidden binary file) in the installation directory.



4. Verify the IP is functioning correctly by using PING, NET VIEW, NET CONFIG, and NET DIAG on the client.
   
   For more information see:
   
   
   • The online help available for each command by typing /?. For example:
     

     NET VIEW /?

     For PING help, type the command without any parameters.
   
   
   
   • The README.TXT file in the Microsoft LAN Manager for MS-DOS directory. Check the table of contents for sections that pertain to your specific installation.
