Have done some searching on the forums, and can't quite find my situation solved. I have a desktop PC running Windows 7. I have an older PC laptop running XP. Just tried to access laptop from the desktop through my home wifi. Got the dreaded "Enter Network Password" dialogue. Using instructions from other posts, I setup and entered in a password in the "Change homegroup settings" window. Discovered, again from the forums here, that Windows XP doesn't give a crap about homegroups. Now I am having a very hard time figuring out what password and username Windows 7 can possibly be asking for when I attempt to access files on the laptop? I understand ( I believe) that it is asking for some username and password set up on the TARGET machine (the laptop), not my PC. But I recently re-installed XP on the laptop and specifically setup no passwords of any kind, although I did created an admin account called "Brian" (my name). Help? Where to find target machine username and password?
