How to fix an issue where you are unable to open User Accounts in control panel in Windows 2008

I had a Windows 2008R2 server joined to a domain. I wanted to add a domain user as a local admin but when I clicked on “User Accounts” in control panel, nothing happened. I logged out then logged back in and it still didn’t work. I rebooted the sever and still had the same issue.

The fix for this is to create a new shortcut that points to %windir%\system32\netplwiz.exe  and then you can access User Accounts.

How to fix mapped drives disappearing during the day on Windows 8

I had WIndows 8.1 users reporting that their mapped network drives would disappear before their eyes in Windows Explorer, then reconnect one by one. This problem was not occurring for Windows 7 users. The drives were mapped by group policy, and this is where the problem occurs. Periodically, Windows 8.1 will do a group policy update, and if the group policy Action for the mapped drive is set to “replace” , it will disconnect and remap each drive.

The solution to this is to set the action in the mapped drive policy to “update”  and you won’t have this problem any more.

NOTE: if the action box is greyed out, you need to click on “common”  tab and then  untick the box that says “Remove this item when it is no longer applied”
