I have a question about the default administrative shares in XP, if anyone knows the answer..

Is it possible to access the administrative share on a computer that is NOT on a domain from a computer that is on a domain? Or for that matter, from 2 computers that are not on a domain? I can access the administrative share of my laptop (on my companys domain) from my home pc, but the reverse will not work.. I think some security / network settings are modified when a computer is joined to a domain, I just need to figure out what those settings are, so I can allow my non-domain computer to be accessed by administrative shares.

Usually you would think you could force the machine to log in as a local user on the remote machine, but, it seems, that at least in XP, it won't let you do this by default. Either it will completely gray out the user name (with Guest as the default), or it won't allow you to use the remote machine / user (REMOTEMACHINE\Administrator)..

Any ideas?
