In addition, you can goto the Default Domain Controller Policy:
Expand Local Policies,
In detail pane, double click:
"Microsoft network server: Digitally sign communication (always)"
Ensure that Define this policy is checked
Select Disabled
Click Ok

This will allow backward level clients to authenticate into the domain. This
is a method we use to allow DOS based clients to access data on a 2k3 DC
during our auto classroom setups for the Win2003 classes, and applies to W9x
and NT4 since their authentication methods are similar.
