How can I connect a Snow Leopard computer to a Windows 7 homegroup?

"First of all HomeGroup is not an actual network so your question has noting to do with that just so there is no confusion. (Its a virtual network that is between win7 machines)
Check your network and sharing center that you have your File sharing turned on and the folder that you are tring to share is actually being shared. every new network you connect to windows shuts down this option for security concerns. than you have to check if its a publicly shared folder. if it needs a user name and password just use the ones that you use to login to that win 7 machine. with out further info i dont think i can be more help if i was any at all?"

"In win XP you can share some folders. Is this removed from win7? Also in winXP you had to create a network or something like that in order to see you PC in the network and make the folder available for accessing.

If you are watching in the finder and you select the win 7 pc. You can ""connect as"" perhaps you have to logon?"
