There are many users begin to use Win7 for testing purpose. They met the following issue if not join domain: 1. If they try to access the file server by \\IP, a prompt will show to ask them for account and password, but even you key in the right login, it still remind as "unknown user name or bad password" 2. It's ok to access the same server by using unc path like \\servername. 3. It will failed if you try to access \\servername with the account from other domain. For example, if the server is in CN domain, it will failed to login with a TW account.Can some one help me? Thanks in advance!Peace&Love
