Administrator Sharing Security Permissions Ownership

I believe I have a unique problem since I have searched this forum and have found nothing like it.

My account is an administrator & have no other accounts. I originally set up a homegroup between my 2 laptop PCs but have deleted the homegroup since I can't get the network sharing to work.

When I look at the Network list from Computer A, I can see both Computer A & Computer B. Since I am sharing the User Folder I can see both A & B, open both A & B and when I look at the Properties I see the dialog box immediately and the Computer A Properties has both Security & Sharing tabs, Computer B Propertes has only the Security tab which I believe is correct.

Computer B is entirely different. Again both computers only have adminstrator accounts.

When I look at the Network list from Computer B, I can see both Computer B & Computer A. Since I am sharing the User Folder I can see both B & A, I can open A's User Folder but not B's (its own folder) and when I look at the Properties I see the dialog box of A immediately and the Computer A Properties has Security tab only (as it did above) & Sharing tabs, Computer B Properites (its oen User Folder) takes a long time to open & it Properities only show the Sharing tab, not the Security Tab. Since I can't see the Security tab I can't change the sharing. The Permissions & Ownership look correct. How can I get the Security Tab back.

I have tried sttting the UAC to never notify, but this doesn't do it. I have tried a system restore & it doesn't help.

Oh I can go to the C: drive & access B's files so I'm not really hung up, but I don't understand why there is no security taab even though I am the administrator. I'm hop[ing its just a regustry key.

Thanks for listening

Here are the screen shots from the offending computer

I'm not home right now, so I will check the version - But yes my problem seems to be no security tab even though I'm the administrator

If you allowed the C drive to be shared with Everyone using Properties>security permissions tab it would override the security on the User folder which might pervent the Security tab from being shown on the User folder. So maybe you should try to "unshare" the C drive by using the Security settings tab and see if that restores your Security tab on the User folder.

It's safer from a Security stand point to share the User folder rather than the entire drive.

OK I'll try that tonight.

What about the fact that in the Permissions Dialog Box only Everyone is shown? Is that normal?
