Help! I've been searching all over for solutions and can't come up with a fix. I've tried this (http://windows7forums.com/windows-7-support/53442-access-denied-my-files-another-pc.html) and this How to Share File with Group and User Permissions in Windows XP and this How do I get round Windows 7's file permissions? - Microsoft Answers and this http://windows7forums.com/windows-7-support/3975-change-workgroup-name-windows-7-a.html but I can't seem to get it to work. I have 3 pc's in my network. I've networked win2k machines with win98, 95, and XP, but this one has me stumped. Machine 1 - Dell 2.66 running win7 32 bit. (M1) Machine 2 - Generic 1.8 running win7 32 bit. (M2) Machine 3 - HP i3-2310M CPU @ 2.10GHz running win7 64 bit (M3) They're all Home Premium. I can push or pull files from M1 to M2 and visa versa. But I cannot pull or push between M1 and M3. After several hours this morning I was able to have M3 pull from M2, but I could not push and I could not get M2 to push or pull from M3. I am at wits end. I have no idea why I was able to get M3 to pull from M2...all machines have the same settings. The error I get when pushing or pulling is: Can someone please help me. I'm not opposed to rechecking everything, perhaps it's something small, but I've been trying to get this to work for weeks and can't seem to figure it out on my own. I wish they' would have left things alone with the networking like win2k. Also, quick note, the workgroup name and the network name are the same...don't know if that has anything to do with it. Thanks!
