Hello everyone

I did everyting that I could, but I can get it working... here is my problem !

I have a Windows 2003 SBS with Exchange 2003 and ISA 2000.

My workstations are using Windows XP (dutch) with Outlook 2003 (dutch).
Everything is working fine, except that I can send as another user. I'm
administrator on the workstation and on the domain and server. I don't want
to " send on behalf of "... but " really as "that" "

I've searched all over the web, and I did everyting that they suggested. I
looked on www.msexchange.org and on that forum, but I can't seem to find the
solution

I hope that someone can help my...

Let me know !!!

Greetz,
Dave
