Ignore that. What windows is doing is trying to connect to your mapped drive BEFORE the network has time to get an IP address and find the PC. I don't know why microsoft hasn't fixed this yet. They should have it be a delayed start or it doesn't try to remap it till AFTER it gets an IP. stupid Microsucks XD. But yea i have my Media Drive shared out or my GF and room mates can access it. My laptop and my PC use the same username and password (So it doesn't give you any logon credentials) and i wanted them to logon as the Everyone user but they only have Read. this way i don't have to give out my password, or create multiple accounts, or have to worry about them changing anything. I kept running into issues and i pretty much found out what i had you do. remove homegroup, I had to take my media folder and add the Everyone user to read permission not only on the share permission but on the drive permissions itself as well. but yea now if you want someone to access it just have the browse to your PC and then use the user and password on that PC. If you want it so everyone can read it then add the Everyone to the Share premissions and then Add the Everyone (With read only permissions) to the D drive Security tab itself as well. This will allow them to connect to the PC with out a username or password and read the stuff but not modify any of it.
But yea Windows 7 sharing can be a pain. I don't do homegroup bc yea that works with Windows 7 PC's on the same network but its easier to deal with out it. Also if a windows 7 is on a homegroup and you have a XP machine trying to connect to it. Forget it. Won't work. have to remove homegroup lol. Lame i know.
Any other questions?
