I have a wired network here at home and am the only user on both machines. Both are XP pro with NTFS and both have simple file sharing turned off. I have enabled full control file sharing of each C drive, which makes my life easier, but cannot figure out how to share the Program Files folder. Any help is appreciated. Thanks.

Normally you can't share programs by running a program installed on one computer from another. Exceptions are if the program is a network version. Otherwise you need the program installed on the local machine. You may be able to work with files from the other installation.
All the above is by design. Multiple user versions of programs are more expensive than single user.

You will note that when you right click on Program Files and choose Sharing, it says at the bottom of the window
"All the options on this tab are disabled because this folder is used by the operating system."
You can do anything you like in Program Files on the same drive, C or whatever XP has assigned to the partition Windows is on and is running from, but you can't share access to it with other computers on a network, at least not in XP.

- If I right click on Program Files it does allow me to set sharing permissions, however when I try to browse it from the other computer I get the "not accessible" message
- I do not want to run programs installed on one computer on the other computer, I just want to share the files
- start>run>\\computername\c does show the other computer's c drive fine and I can browse most of its folders, but not Program Files now Windows
- start>run>\\conmputername\c$ gives a logon window, but no matter what I put there I get the not accessible message.

"If I right click on Program Files it does allow me to set sharing permissions, however when I try to browse it from the other computer I get the "not accessible" message"
It doesn't on mine, a relatively fresh install of XP Home. I doubt whether it matters which XP version you are running. All the boxes where you place a checkmark are greyed out.
If there is a way of getting around that, I've never heard of it.
It does let you share the contents of it with any other users using the same computer, if you drag it to the Shared Documents folder.
I have file and printer sharing turned on, and other computers on my local network are able to access anything on the XP installation except the Program Files folder on the actively running XP installation (you may be able to access a Program Files folder on another XP installation on a computer that is not running)."....when I try to browse it from the other computer I get the "not accessible" message"
If that's the only one set as shared you can't access, that's by design.

Any files generated by modern applications will be save in a subfolder somewhere in the My Documents folder.

I hope you on't mond my asking but what is your reason(s) for wanting to share program files folder. Are you the only user on both machines?

- yes I am the only user.
- I want to share both the Program Files and the WINDOWS folders on both machines. I have programs and data there that I need to share between computers. I realize I could work around this, but am not looking for workarounds. When I say data I do not mean things that get put into My Documents, I mean editable ini files, config files, etc.
It doesn't really matter what I am sharing or why I want to, I am just asking if anyone has advice as to how to get this working. In searching the net it seems others have done this. Thanks for any help

Since you are using XP Pro you might have an issue with the way permissions are set up. First of all, since you are not on a domain (I assume) you should use the same user name on both computers to make setting easier.
Try this:
Right click on the My Documents folder and go to sharing. Check the box to enable sharing. Set the user limit to "maximum allowed". Click the "Permissions button". In the permissions window, delete any groups or users that are listed. Then click "add". Type "everyone" for the object name, click "check names" then click "OK". You should see "Everyone" listed in the "Groups or user names" filed for Share Permissions. Highlight "Everyone" then make sure all the "allow" boxes are checked.

Well I figured it out. In addition to needing simple file sharing turned off, you need to also create an administrator-priveledged user THAT HAS A LOGON PASSWORD on the target machine whose drive you want to access. (Since no one uses my machines but me my logon passwords were blank)
Also, instead of just navigating to the C drive through network places, you need to first logon to the administrative shares of the target machine (such as start > run > \\computername\admin$, then key in the above adminstrative username and its password).

even easier, with no change needed to passwords or priveledges
reg file that allows remote blank password:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"limitblankpassworduse"=dword:00000000reg file that disallows remote blank password (default):
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"limitblankpassworduse"=dword:00000001

I've read these comments with interest. I have a similar problem, but not with a network. I have one computer running windows xp with 2 users. I am the "administrator" and can access the "Program Files" folder. But my husband cannot. So if I install a new program, my husband cannot run it when logged on as himself. I did recently install a wireless router for my son's laptop when he's home from college. And after reading all these comments I think that this problem started after that. So I need advice on how to give access rights to the "Program Files" folder to another user on the same computer. Any help would be appreciated cause this has been driving me crazy!

How to take ownership of a file or folder in Windows XP
http://support.microsoft.com/defaul...Read it carefully - you probably have to boot into Safe mode to get it to work.
If you do that for the Program Files folder, by default all subfolders will have the access denied problem taken away as well.
All users must have administrator rights if you want all users to be able to access the files.
