We have 3 terminal servers (Windows 2003 SP 1 with 4.9 novell client) that work very well with bordermanager html authentication and the bm plugin. On one server I installed the Zenworks 7 client and the 4.91SP2 novell client and enabled group policies. Since then, when I enter all the information in the authentication html page, I'm redirected to an error page "DNS error" and the following in the link box ( is the ip address of the bm proxy):

What could be the cause ?

Thank you,
