Description: CIFS user authentication from a Windows XP client fails on the first attempt. The second time the user attempts to log in, authentication occurs as expected if NTLMv2 is enabled on Windows XP clients.
Cause: Windows XP sends the client machine name as a domain name. For the second attempt sends the actual domain name.
Action: Pass the user name in domainname\username format.
For example, if you are using net use command to map a CIFS share following is the command you can use.
net use <device name> \\<computer name or IP address>\<share> /user:<DOMAIN>\<USER> <password>
net use * \\192.168.100.1\CIFS_VOL /user:BLR\cifsuser1 <password>
In this example, net use command is used to connect to the share named CIFS_VOL on a computer with IP address 192.168.100.1. The CIFS_VOL share will be mapped to the highest free drive letter [*].
net use e: \\192.168.100.1\CIFS_VOL /user:BLR\cifsuser1 <password>
In this example, net use command is used to connect to the share named CIFS_VOL on a computer with IP address 192.168.100.1. The CIFS_VOL share will be mapped to e: drive.
NOTE:NTLMv2 authentication is enabled by default on Windows 7 workstations.
Error: Password has expired.
Cause: Password expiry is set for security purposes. The password has expired.
Action: Reset the password and try to log in again.
Error: Only folders to which the Public trustee has rights are visible.
Cause: If you have logged into a Windows workstation and see folders assigned only with Public Trustee rights, it is either because you have logged in with an incorrect user name or have logged in as a guest user.
Action: Log in with correct credentials.
Cause: The password is incorrect.
Action: Provide the correct password.
OR
Cause: Universal password is not set for the user.
Action: Set the universal password for the user.
OR
Cause: The client and the server have incompatible LMCompatibility level settings.
Action: Check for the LMComaptibility settings. For more information, refer Setting LMCompatibilityLevel.
