NTLM authentication login failure

[Guest]

I can login to our shared file server on a mac and using XP; when I try the
same method using Vista it fails at the authentication point (after entering
username and password). Someone suggested changing the NTLM option on local
security policy to "NTLM response only" but this did not solve the problem.
Any other thoughts?

You need to either downgrade the Vista system to use NTLM V1, or upgrade the
other computer to use NTLM V2.
