We have installed Webroot Enterprise SpySweeper on our network. Its
presence is causing the workstations to hang during login. Novell's
solution is a bit lacking: http://support.novell.com/cgi-

Instead, we fixed the problem by creating a dependency for the Webroot
Services based on Explorer. This causes the Webroot stuff to load last,
allowing the login process to complete.
