Permissions Differences - XP vs. Win7?

Hello.

I have two machines, and I've created a user with the same name on each machine. Under XP, I had full control of files across the network, simply because my username and password were the same.

Under Win7, I can't access files over the network on the other machine, even though username and password are the same. Once again, user is an admin. What's changed?

Data follows:
Workgroup = MEW
Machine1 = MEW7
Machine2 = MINIMEW
Username = MEW (admin)

NTFS Perms:
Administrators = full control
Authenticated Users = read & execute
MEW7\MEW = full control
MINIMEW\MEW = full control

Share Perms:
Authenticated Users = full control
MEW7\MEW = full control
MINIMEW\MEW = full control

Under XP, it seems a user with the same name and password was recognized as the same user on the other machine. This seems to be no longer the case under Win7, as user MEW only has read & execute perms on the corresponding network shares.

How do I get Win7 to recognize MEW as the same user on each machine? (If that's not possible, how can I use groups to give only user MEW full control of files across the network? (I've googled, but I can't come up with any info on the differences between XP and Win7 networking. Can someone point me to documentation or a tutorial?)

My laptop is running Home Premium, and my desktop is running Pro. Both machines are x64. Obviously using a domain account is impossible, as my laptop has only Home Premium on it. (Also, I'm not running a server in the house.)

Also, I'd like to be able to access Admin shares periodically. When I attempt to map C$ and use my "MEW" login, I'm told I don't have the proper permissions. I suspect it's the same perms issue in this case as the one above. Help much appreciated!

TIA! :)

That is actually a security feature. XP was lax in that respect. Lets say on a network there are two john smiths and both are dumb enough to use 1234 as their passwords each could access the other.

In win 7 each would be rejected.

The way to make it work is to use the fully qualified path name IE network/machine/user/password

As to admin share it is the same network/machine/Admin/$C:

Hope this helps

This isn't XP "not even close" so forget everything about XP sharing you ever learned.

Only use the same user name and passwords for XP machines in your network and only if you have more than one XP machine, it makes no difference for the Win7 machine. This is only to avoid getting those pesky password prompts that XP is famous for. There is also another way to defeat the passwords by using a guest account in XP.

Do not use the same user name on your Win 7 machine or it won't show up on network. Also, do not use the same user name as your Workgroup name "MEW".

First set up a Workgroup on the Win 7 machine then join that workgroup from the XP machine after running the Network set up wizard on the XP machine, then set up permissions accordingly, you may need to type "Everyone" in XP permissions in order to share with everyone on the network.

Sorry, my workgroup name is not the same as my username. I just typed it incorrectly in my original post. (I've fixed it now.) I'm not trying to network XP machines along with Win7, as I've just retired my WinXP machines and now have two Win7 machines. I was imply providing info on what I could do with XP that I can't with Win7. I'd really like a pointer to a summary of how Win7 networking differs from WinXP. Can you point me to something? :)

Actually, I read in another post that Homegroup networking interferes with share network access. Sure enough, once I turned off Homegroup on each machine, my username/pwd combo gets me full control of my files on the other machine. Interesting, eh?

Unfortunately I don't understand your syntax for accessing user & admin shares. I'd like to make sure I'm doing this properly. Would you please clarify, and also can you point me to some documentation? I've searched Technet and haven't come up with anything. I guess I'm not using the right keywords. Help much appreciated. :)

Thanks!

OK, now I'm really confused. I can access my shared data across my workgroup with an account that uses the same ID and pwd. All I had to do is turn off Homegroup!

I can also access administrative shares now that I've enabled them by editing the registry:

Turn on Admin shares

It seems Win7 networking is not so different after all.

Thanks anyway....
