Windows 2000 workstations on my Windows 2000-based network take 15-20 minutes to boot up: 15 minutes to Ctrl-Alt-Del signon and 15 minutes to desktop. Problem does not effect Windows 98 and Windows XP Home Edition workstations. Both boot normally and run smoothly.
Installing Windows 2000 with Service Pack 2 on an HP Brio and Compaq Deskpro with latest BIOS update. System ran well before addition of Linksys Router and modifications to domain controller. Have tested installed Windows 2000 workstation, Windows 2000 server, and Windows 2000 Advanced Server with same results on both machines.
(1) Recently installed a Linksys Cable Router onto the network.
(2) DHCP is provided by Linksys router (service disabled on domain controller server)
(3) Followed advice of a friend and made some modifications to domain controller server services but did NOT write down the changes.
