the "be more specific " goes to "before I do that and change my own DNS settings, why you don't change the settings with kix without com?" and not to UDF.

Are you a little suspicious about me. You think that am newbee and i want to ask you how can i modify registry?(reminds me microsoft "modify at your own risk")

My first question is about WMI method. Thanks for your try.I like short code is more simple to support my 2500 users with wmi functions than with one UDF with 2 pages of code.

Thanks ,
