Tried leaving the homegroup and rejoining, tried leaving the homegroup and creating a new one. But still problem persist.
EDIT: Just now made a windows 7 credential on Computer D with Computer A's information (username/password) so far it's working! Will see how long this last though...Haven't restarted computers yet.
I rebooted once already and it was still working, had the laptop off for a couple days now and will turn it on and check again. Reason: Because that's what happened last time after a reformat. It worked just fine and then after a couple days of not using it all of the sudden it didn't work. Will post back (edit this post) in a few minutes if it worked...
EDIT: Yay it still works! Oldly it wasn't working until I created a credential for it...which I didn't have to do before. But at least now I don't feel like I have to do any extra steps or created un-needed user accounts in order to access my shared files!
I also hope that if anyone else is having this problem with networking and multiple computers that this will help them.
I did it all from the windows 7 machine. I basically had to leave the homegroup on computer D and leave the homegroup on computer C because they were both windows 7 PCs. I then recreated a new homegroup on computer D and added the Credentials for computer A then had computer C join the new homegroup. Computer B (Windows XP) was never a problem (I miss XP!!!)
NOW!!! Santa is dropping (or dropped) a brand new windows 7 computer down the chimney for my kids. It will be wired in and take the place of computer B....Wish me luck!
Going to mark this topic as solved then and if I have any additional problems I'll start a new thread but I think we are all fixed.
Yay I solved my own problem!
