To add a connection to a network drive, you need the following information in advance:
The connection to a http webdav works as well in case of need, but is not recommended due to the missing encryption and should only be used in exceptional cases.
User names and passwords are usually not required, especially in an Active Directory managed network, because your possible shares have already been defined by the administrator. In this case, user name and password are not to be used in any case, because otherwise you would have to adjust your connections again after changing your password, depending on the password policy.
If username and password have been used for connection, there is a possibility to share the connection you have established for all users of this computer.
