More command line info needed

Hi all;
I'd like to do some 'repair' work on XP(problem-locks up loading drivers). I've booted from a PE disk and would like to either rename the "My Documents" folder (to reload XP w/o losing data) or to copy across to another PC on the LAN.

I attempted to use the MOVE cmd to rename the folder but the 2 word dirname gives me a syntax error. When I do a 'Net View' I can see the PC I want to copy to. Will 'Net Use' allow that PC to see the problem child and let me move files across?

I haven't done any DOS work since WIN98 so I'm pretty rusty at this. The HELP info seems to assume the 8 character file naming convention.

Any outside help would be appreciated. Also, any good books on XP cmd line work out there?

TIA,
Keith
