I am looking for how the automatic login may be managed via group
policy on a windows xp computer in a domain. I am wondering is there is
a user or computer setting that disables or enables autologin on a
domain computer. I think we may have a policy effecting this but, I am
not sure where it may be defined or what the setting is.

I am going to setup a computer to autologin by setting the registry keys with ther username and password etc, and want to make sure nothing we have defined is going to be preventing this from working.
