Problem description

When you access a network-attached storage device after you upgrade to Windows Server 2008, to Windows Vista, to Windows Server 2003, or to Windows XP, you may experience authentication issues. You receive an error message that states that access is denied or that the operating system cannot log on the user. This issue occurs even though you provide the correct user name and the correct password.

By default, Windows-based client computers are configured to use only NTLM version 2 (NTLMv2) authentication when the client computers use challenge/response authentication to authenticate to servers. This default behavior may cause problems when Windows authenticates to third-party products that cannot handle NTLMv2 authentication.
