I would think I am like many simmers out there who have upgraded to a new Win7 machine but still have there old one intact. For me that old one is a desktop running WinXP Professional (which I still like and use daily). So I have a new Win7 laptop running Home Premium 64. Here's the set up: The two are connected via a router using Ethernet connections (no wireless). And when these two are running I have no internet connection. Pretty plain and simple.I set up both on the same Workgroup (not a Homegroup).Both have the Username and Password (me), and I am the Administrator.I have turned off Simple Sharing on the XP pc and given full rights to "Everyone"Did the same on the Win7 pc but seems to be easier to set that up.So here's the kicker - I can open, read, edit, etc., no problem from the XP machine on files, folders and drives on the Win7 machine. But from the Win7 pc I cannot access anything on the XP pc? But I do see the pc on the network, and the test folder I have set up to share.It's gotta be permission thing? Been reading a lot of forums about this but seeing a lot of different ideas, answers... so far nothing working. My goal is to have full access on complete drives on each pc as share folders would not work for my purpose.Anywho, any ideas as to why I can only go in one direction? Anybody have success with this at home?thx,CLutch

To my amazement, I didn't have to make any user changes on my W7 box on the last reinstall to make my laptop completely access the W7 machine, and vice versa.Both are Administrators with same password, that's obviously important.On my W7 box I have all my HDDs shared, via Advanced Sharing, all full permissions to Everyone AND Administrators (the kicker is, it didn't work with Everyone only). On the XP box though, I have set Everyone only. Not folders but also the whole HDD (or partition for that matter).This is setup in the networking:One another thing: Both computers have IP adresses next to each other (like 150, 151...) and fixed IP setting, with same protocol configuration (subnet etc...) obviously.

Interestung, Word Not Allowed. Your screenshots look pretty much like mine with the exception of the last selection - I have selected "Turn OFF password protection sharing". So I take it you must enter your Username and password everytime you want to access a drive?I only have Everyone added in my Win7 pc which works completely for me? But I will go back and check the XP pc to see if I have Everyone and Administrators in there. Worth a look. Plus I heard some person had to add or change his UPN??? Bla-bla something or rather on his router and he got complete access bothways - Strange how setups can be so different. But its good to know you can actually share entire drives both ways.Clutch

I discovered that if I use on both computers same username and password (in my case its the main Administrator account, which I find better to be logged in with than anything else, I have least problems with that, and been doing that since oh WinNT I think...), I don't have to enter any password. And if I use a different password, than enter once and save. That's it.Password-protected-sharing is VERY important, because I read on many occasions that sharing in windows is password dependant, even if it's a simple password as 0. For instance, my Seagate Theater+ can't access Win7 drives over Network if I turn off that...I have to have the password, then save it there, and voila, it accesses always without any trouble.I think also that because I have a password, all shares have to be shared to Administrators (and NOT Administor), because I wasn't able to access them with Everyone only. I read somewhere to add Administrators, tried it and since then never had a problem.Huh, UPN? ##### is that?I never changed anything on my router... I think the poor thing has been running for 2 years now without interrupting. And I think it's some 9 years old or so.I don't think it's as much up to the setup or router, but rather a correct setting. And they are not far away. Just have to know where to look. So in short: turn on pps, use a password, and share to administrators. Log in with Administrator/your password (save login).

Thx, mate for the suggestions. I will give 'er a go...

Tell me how's going, interested to know if it solved it...

Just a reply to an old thread if anyone is interested. I was never able to get it to share both ways. But no I am in the process of moving so I have packed up the XP PC. What I think I will do once re-settled is to do a clean install of XP on that machine and then re-try connecting... then again by then I may upgrade that one to Win 7 but I would like to keep a vintage XP around the house for testing purposes.
