Since you mention authentication, I assume you're asking about sshd.  I
also assume you've eliminated the client from the equation by using the
same host to ssh into the machines in question.

In what situation do you get "access denied"?  Do you use public key
authentication?  Are your permissions identical on sshd support/config
files?  Are /etc/passwd and /etc/group files up-to-date on both machines?
Did you try running sshd with debugging flags?  Do you get any messages in
the log files or in the Windows Event Log?  What does "ssh -vvv" (yes, on
the client) report when connecting to both working and non-working
machines?

If worse comes to worst, and the above doesn't provide any clues, there's
always strace (the output of which from both machines can be compared
easily enough).
