PROBLEM:
"I had DOS PXE boot imaging working fine for months until recently, when it started giving the following errors:
Invalid drive specification
Unable to map network drives
I put a pause in the batch file and the error given is:
Error 53: The computer name specified in the network path cannot be located."
SOLUTION:
In my case I deleted the DOS bootdisk and recreated the DOS bootdisk.
The problem on my side was the incorrect user ID and Password that the bootdisk uses to map the drives.
Correct User ID and Password entered and drive mappings successfully completed.
