Hello to everyone ......i have 1 hard disk with 2 partions ....c:with is and d: for the data .... When i went to open a folder in the disk d : tha windows told me that i must have admin privileges to open ....then pc scan this folder to see the contents of this folder ..... When i right cloc this folder and i went to properties in the security section i see those strange groups and usernames .....like the folowing photo ...http://i243.photobucket.com/albums/ff1/fuzzjo/Untitled-7.jpg this issue is so strange ...it told me to open this folder with admin privileges ...and at the security tab i saw that groups and account .... Can someone help me with that ?

Is this computer part of a Domain? It is displaying SID instead of an actual user name. It could be name resolution issue, deleted accounts etc etc Santhosh Sivarajan | MCTS, MCSE (W2K3/W2K/NT4), MCSA (W2K3/W2K/MSG), CCNA, Network+ Houston, TX http://blogs.sivarajan.com/ http://publications.sivarajan.com/ This posting is provided "AS IS" with no warranties, and confers no rights.

Hi, Please enable Administrator account on the machine and login on the machine as administrator, and then remove the "Unknown Account" in Folder's Security tab. After that, please add your current account in the Security group and restart the machine for a test. For more information, please refer to the link below: delete this account unknown Thanks, Novak

why i saw those users in this folder only ....I dodnt have any same issues with other folders The folder with the problem is in the second partiotion ......

Somebody might have assigned a user permission to that folder. That user is no longer available or deleted. You can delete these SIDs if it is not in use or add the actual user name to the permission tab.

the user permission to that folder can excist after a format ? because my machine have a new config after format

Can you tell me whether the folder is a system folder or a local folder? Is it in system drive or other local drive? If the folder is a system folder, the user permission to that folder won't be existed. Otherwise, the permission may be already existed. As Santhosh was mentioned, the issue may occur if the folder permission was changed by Someone else. Please try above suggestions to delete the SIDs. Thanks, Novak

The folder called (arts ) for example is in the second partions ...I have 2 partitions ...C: and D: SO I delete the sids ....bit i cant understand ....who changed the permition ...The machine is fresh copy ....2 weeks from format ...i dodnt change antthing .....and now i saw the folder with a closed lock on it why ? i see in the share option a user with unknown name like this photo http://www.windows7taskforce.com/view/2678

Hi, To clear the closed lock on the folder, please open the folder's Properties tab and then add "Users" to "Group or User names" in Security tab. Regards, Novak
