I have now officially given up and am seeking help to regain some sanity.
Scenario: All new Dell PE830 with built-in Broadcom 10/100/1000 and additional Intel PRO/100B 10/100 adapter. Windows Server 2003 Standard with SP1 and updates. ENS won't load no matter what. "The ENS driver was not loaded. This may mean that it is missing or has been disabled"
Tried solutions: Demoted this DC to standalone server. Disabled all network related services (ICS, RAS, etc). Removed first one adapter, then disabled the other in BIOS. Uninstalled DHCP, DNS, WINS servers. Reinstalled WinGate numerous times, including wiping the registry and directories.
qbikhkxp.sys is present in windows\system32\drivers.
Is there a way to get a more intelligent error message from the ENS driver?
