Hi, Please check whether there are any error message related to this kind of issue in Event Log? If so, please provide the exact information. Also, it seems that something may have made the local Windows account database (SAM) corrupted for that account. So I suggest you to create a new admin user for a test.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Looks like a registry mess. Better backup any files needed and install the OS clean (or sysprepped) Windows MVP, XP, Vista, 7.

Have had a weird issue pop up on a Win7 Pro 32bit installation. When attempting to view the properties of a local User, within Local Users & Groups, I get the following error message. ********** The following error occurred while attempting to read the properties for the user %username-here%: An internal error occurred ********** Interestingly enough, when I go to view the properties of the localgroup Administrators, there are no users listed within the Window - however, if I try to add a user to that group, it tells me that the user is already a member of the group (which this particular user should be). When I pull a NET LOCALGROUP ADMINISTRATORS via CMD, I get the following error. ********** System error 87 has occurred. The parameter is incorrect. ********** But yet, when I pull the same for NET LOCALGROUP USERS, it works just fine. Anyone have any ideas on this one?
