Outlook 2003 users need admin rights?

I am setting up a new workstation (running xp pro) on our SBS 2003 network. I joined the domain however when logged in on this new workstation under the users acct, I can not run Outlook 2003, I get a window that says “cannot start Microsoft Office Outlook”. If I log on as the admin account, it runs fine…

I do not know if it is related, however I can not download files from IE 7 either when logged on as the “User”. I have to log on as admin to download a file like Adobe Reader for example.

Additionally I get that runonce everytime I open IE7 no matter how many times I click through it and save the settings.

Are these related problems? Is there a solution?

Thanks, Robert
