Outlook freezes trying to attach a file

MS Outlook freezes when trying to a attach a file. Delay sometimes can take as long as couple of minutes. Windows Explorer can also freeze at the same time.

This behaviour is most often caused by a Disconnected Network Drive or My Network Places shortcut pointing to non existing network location. Simply disconnect the old drive or delete offending shortcut and problem should be fixed.

If this doesn't help you can try deleting Temporary Internet Files and clearing Internet Explorer History.

Enable remote desktop remotely

Remote Desktop Connection

If you have access to a computer enabling remote desktop is done this way:
Control Panel > System > Remote (tab) > Allow users to connect to this computer

However you could be in a situation when Remote Desktop on a computer is disabled and there is nobody who could enable it.
If you have network access (local or via VPN) to the remote computer, you can easily enable remote desktop without having physical access to the PC.

  1. Start > Run > Regedit
  2. File > Connect Network Registry. Type remote computer name and click OK.
  3. Navigate to [ComputerName] > HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server
    change fDenyTSConnections value from 1 to 0.
    Enable Remote Desktop Connection via Registry
  4. Restart remote computer
    • Start > Run > CMD
    • shutdown -m \\[ComputerName] -r
