Please be gentle with me - I'm new to this! I'm trying to introduce two Win 7 Pro HP Probooks to our Win 2K domain. All XP models work fine. These two will allow themselves to be "introduced" to the domain but then, after rebooting, wont recognise the admin username and password I JUST used! If I log on locally I can browse the network and the admin credentials are accepted then. I can ping the server. The Probook is assigned an internal IP, given from the network. I've Googled everything but am still unsuccessful. Any help at all would be greatly appreciated.
