Citrix PS4/Outlook Problem

Hi,

I have a problem launching an imbedded link from Outlook 2003. I click on
the link and it launches IE, but the page remains blanc and
the message "the page cannot be displayed, cannot connect to server or ´dns"
appears. With a refresh (F5), the web page does come up.
Also when I first start IE6 I have no problem. When I log on als
Administrator I've no problem, only with users. DNS and proxy settings are
for sure correctly, the problem we had also with our old servers (PS4,
Win2k, Office2k), for several users it has worked.


The problem is discribed also in the following link:
