Proxy Server' Security certificate

i am trying to setup RPC over HTTP on a outlook 2007 environment.
i have installed the certificate under trusted certificate authority and under local computer specifically, and the import was successfull. the OS i have is windows vista business. i have configured outlook the same way i did it on a windows xp OS SP2 where it worked fine.
Whenever i open outlook, it prompts me for the my username and password, after that i get the message:
"There is a problem with the proxy server's security certificate.
The Security certificate is not from a trusted certifying authority.
Outlook is unable to connect to the proxy server www.*******.co.uk.
(Error Code 18).

Well you have to install the certificate properly.
1.- Run IE explorer as an administrator.
      Right click on the icon and run as administrator.
2.-Go to the site where you can dounload your certificate.
     Example: https://hq.youserver.com/remote
3.- If you don't have a trusted certificate, On the certificates warning, Click on "Continue to this website (not recommended). "
4.- Click on the certificate on the right side of the address bar then click on view certificate.
5.- Click on install certificate follow the wizard.
6.- ONLIKE XP, Choose Radio button: Place all certificate in the following store and click on browse.
7.- Choose "Trusted root Certification Authorities", then click on next  then finish.
That should do it.

thanks guru, that's what i did on my personal laptop, but i Guess that i have found the problem.
the SBS 2008 and by default it uses remote.domainname.xxx as domain name. i meant previously when on sbs 2003, it was different and to be honest i din't have that remot.mydomain.xxx valid, so what i did is that i have created a new MX record redirecting the mail flow to the remote.mydomain.com, and it worked like charm. i
