Problems with LogonCount?

[Tripredacus]

Just throwing this out there, not sure if dealing with goofy end-users or what, but has anyone ever encountered any problems after setting a fairly large LogonCount setting for sysprep?

For example, I've "heard" of these (from the support people) but we can't reproduce these issues:

1. PC prompts for password instead of autologon (way before the amount of logons specified for this object)

2. PC prompts for user to change password

3. Password expires?! and machine can't logon.

I am fairly certain that things are being done with these machines that are causing this issues, and not so much that the XML is causing this, however, I also do not know exactly what Sysprep does to the account in the system when you specify to create an account, password and specify LogonCount.

As an example, I have one image set LogonCount to over 4 million, but the users of this image are encountering all sorts of issues (like #1 above) within weeks of using the PC. Other images I have set the same LogonCount setting to are not having or, at least, reporting issues like this.

When I get the chance to test, if you Logoff the user account, then relogin (manually) and/or reboot, will the next reboot login automatically?
