I have networked with full shares with all 5 pcs. This whole homegroup/workgroup mess is solved for me.What I was attempting to do is network all 5 pcs with administrative shares, but like many others, I was having issues with the 7 seeing and accessing the XP boxes. I have 2 xp, 2 vista, and 1 win 7 64 bit. I've attached a screenie to show 2 things.... 1. Homegroup only works on Win 7 boxes. It clearly states that in the Homegroup information. Once I disconnected from Homegroup I was allowed to go into network, and select workgroup. Once workgroup was selected, it's just setting up your own desired shares. I was assuming Microsoft was just doing their obligatory renaming and that Homegroup and workgroup were the same...they are not. And since Homegroup is valid only on 7 boxes and not taking MS legacy OSs into consideration, I dont know why they'd even add it. 2 On the left under NETWORK is where I connected to workgroup. I hope helped at least 1!
