In a DOS environment when attempting to run a "NET USE F: \\servername\sharepoint it may return:
"Error 53: The computer name specified in the network path could not be located".
This will happen in MS-DOS or FreeDOS typically but can happen whenever you use the NET USE command at a DOS level to attempt to map a network drive.
This is a problem is typically with hostname resolution. DOS does not allow an IP address to be mapped directly. It is limited to a hostname such as "server1" instead of "192.168.1.1".
This error can show itself in many different environments and situations. The most common solutions are the following:
- Enter a valid entry in the LMHOSTS file.
- Make sure that you are attempting to map to the hostname of the computer and not the IP address or FQDN. Check the mapdrv.bat.
- Make sure the hostname that you are mapping to is a valid DOS hostname. This means no spaces, forward slashes, dots, or other non-alphanumeric characters.
- Make sure that the computer that you are connecting to will allow a DOS client to connect to the server. (For example, a default Domain Controller.)
- Verify that file sharing is enabled and that the sharepoint is a valid share.
Troubleshooting steps include:
- Try to map the network drive to a different physical sharepoint, preferably a simple Microsoft Windows 95*, 98*, NT*, or 2000* computer that is non-server class.
- Make sure that the sharepoint has everyone and full control is enabled (only for troubleshooting. You can change it back after the solution has been found).
- Create a different sharepoint on the exact same server and attempt to map to that sharepoint.
- Simplify the network so that the mapping is not crossing any subnets or layer 3 devices. You can do this by simply connected your DS server and client computer into a simple hub and then plugging the hub into the backbone for backbone support.
- Disable Plug and Play in the BIOS (if the BIOS has that option).
- Disable Fast Boot (or similar terminology) in the BIOS (if the BIOS has that option).
- Try to map the same network drive from a different physical client computer.
