Network Directory Security Credentials
This dialog box appears only if you specify a network directory. Enter a user name and password that has permission to use the network directory.
Important
If you specify a user name and password to connect to a network drive, all Web server access to that directory will use that user name and password. Choose the user carefully to prevent possible security breaches. For tighter security, use the IUSR_computername account (the anonymous user) for the computer on the network.
