Why am I not able to login to the NAS with a valid username and password when I connect with Windows explorer?
This is a limitation of Windows.
You may already logged in to the NAS from the PC with a different username.
You cannot login to the NAS with another username from the same PC unless you logout first.
To solve this problem, close Windows Explorer and run the Command Prompt in Windows and input the command "net use".
Check if there is connection to Ciphertex NAS listed.
It will look like "\\xx.xx.xx.xx\ss", where "xx.xx.xx.xx" is the NAS IP address and "ss" is the share name.
It may also look like "\\xxxxxxxx\ss", where "xxxxxxxx" is the NAS Name and "ss" is the share name.
If yes, input the command "net use \\xx.xx.xx.xx\ss /d" or "net use \\xxxxxxxx\ss /d".
This will close the connection and the next time that you run Windows Explorer, you should be able to connect with the new username.
