Assuming that it's the dialog that is annoying you (it's not a problem per se, just regular security protocol), it will only go away if you get SSO (Single Sign-On) to work.
If your QlikView server resides in a different domain than the user you are currently logged in as, this can be accomplished by providing a trust relation between the two domains. Ask you SysAdmin about trust relations between domains.
If your server hasn't been added to any domain, please do so. A local machine domain cannot be forced to recognize you if you do not enter credentials that belong to a locally defined user. SSO only works in Active Directory.
