A. A. When you select "Map Network Drive" from Tools menu in Explorer and click the drop down box for the path, Explorer checks the HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Network\Persistent Connections area of the registry for a list of old/current drive mappings. To remove items from the list (or add) perform the following:
- Start the registry editor (regedit.exe)
- Move to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Network\Persistent Connections
- In the right hand pane you will see a list of values a-z and each value will have a value like "\\<machine name>\<share>"
- To remove a map, select the letter associated with it and click DEL
- You should now edit the Order value and remove the letter you have just deleted.
- If you wish to add a mapping select New - String Value and enter a name of a-z (use one that is not in use) and press enter. Double click on your new value and set to the share name, e.g. "\\johnmachine\d$"
- Edit the Order value and add your new letter to the end of the string.
- Close the registry editor
- Start Explorer and your new share or removed share will have taken effect.
