Session Error on IIS Web Remote Administration Tools - IIS 6.0 W2K3 SP

Hello,
I am trying to use the Remote Administration Tools on one of the customers
server and am getting the following:
---------------------------------
  Remote Administration Tools
 
  Your session on the Administration Web site for adminpanel.mywebsite.com
might have expired, or you might have opened this page without first opening
the default home page.  
 
  If you are not attempting to establish a session on the Administration Web
site for adminpanel.mywebsite.com, then you might have opened a malicious
client script from the Web site that you are viewing. If you return to the
Web site, it might pose a security risk to adminpanel.mywebsite.com .  
 
  To open the default home page, click the following:  
  https://adminpanel.mywebsite.com :443  
 
    Close  
----------------------------------  
So when i go to adminpanel.mywebsite.com , the SSL is established, i get
prompted for username/password, and then i see the homepage of administration
(most of the times). but if i click on anything (except help), it will start
loading ( I almost see the page loads) but it instantly goes to the error
page above and attha time even homepage forward to that page.
I have the Administraiton website set on port 80 and SSL on 443. I tried to
search on the internet and couldn't find much. I tried to run this on the
server and via different places and same thing. I would appreciate if someone
could please let me know if it can be fixed.

Btw, The remote administration tool that i'm talking about is the one with IIS ( by default installs on port 8098 / 8099 )

thanks,
Michael
