Hi Justin,
Domain authentication relies on Kerberos and Kerberos relies on accurate
time in domain. If time between client and server is off be more then 5
minutes (plus/minus) Kerberos authentication will fail.
While this is something I wouldn't want to do in my production environment
this offset can be changed through group policy. To change this edit Default
Domain Group policy. In Group Policy Editor drill down under Computer
Configuration -> Windows Settings -> Security Settings -> Account
Policies -> Kerberos Policy.
