I have a user whose password expiration popup won't appear even though he's within the 14 day window configured within his group policy settings. He's running Windows XP Pro Service Pack 3 logging into a Windows 2003 domain. He is wired on the LAN. Even when he logs into the network, confirms that his network connections work fine, logs off (no shutdown or restart), then attempts to log back in, he still never sees the popup. I would think that this would confirm that the network is already fully initialized. If he logs into a remote server, he sees the popup, no problem. It only seems to be an issue with his PC.
Microsoft has stated that this issue was corrected in Windows XP Service Pack 1.
Does anyone know what else I should check?
