Search for the string CD (in uppercase). You should find what looks like a table of all the dos builtin commands. Move to where CD is and change it to cd (lowercase). Save command.com. Reboot. Since DOS upcases commands before trying to match them against this table, changing CD to cd will prevent DOS matching the command and it will then look for cd.exe in your path. For the last few weeks, I've been running a version of 4.01 to which I applied this patch and haven't had any problems.
