An automatic network domain diagnostic, repair, and mapping tool facilitates access by a user to shared resources on a network. A user provides an address, such as a domain name system (DNS) provided address, of the shared resource and user identification information, such as a username and password. The provided address is checked and repaired if necessary to identify the network server having the shared resource. The identified server is checked, such as by pinging the server, to ensure that it is actually responding. The supplied user identification is checked, such as by querying a domain controller, to confirm whether the user identification corresponds to an existing account. When the checks are complete, and everything is found to be in order, the shared resource is mapped automatically for the user.
