Network Drive Control is a free tool which automatically maps the appropriate network drives for whatever networks you use.
For example, you could have the program map a backup drive on your home network, a completely different set of drives at work, and none at all if you log on to a network you've never accessed before.
Setting this up takes a little work. You must remove any automatic mappings you've set up in Explorer, then manually add the details of every drive you'd like to access: network name, the local drive letter to use, the remote drive path, your user ID and password.
Once it's up and running the program should work largely automatically, although there are tweaks available if you need them. If automatic mapping doesn't always work, you can have the program wait before connecting drives, or disable automatic mapping entirely and leave you to connect drives on demand.
If you run into any other problems, a local Help file provides some useful information. Example: if you connect to a network via a VPN, it'll seem to be a different network than when you connect directly. What to do? Creating two separate mappings should solve the problem-- the Help file explains all.
1. Updated Help file.
2. Added a check when a drive is added, so that it does not conflict with an existing mapping. i.e. You can't have more than one entry where both the Network Name and Drive Letter are the same as some other entry.
3. Indicates if a WebDav mapping reports it is encrypted.
