Logon script question

Hi all, I am trying to configure a logon script to NOT run for any user on a particular server. Our security officer has a new program running on our proxy that alerts him if users are visiting unauthorized sites (porno, etc.) The problem is that when I log into the server for maintenance it will show my profile as visiting all of the sites the users are visiting until I log back off. This is not really a problem but it would be better if he did not have to research who was visiting the site during this time. What I am looking for is a simple

?if computer name = ?server1? then no logon script?

type of command to add to my logon script. Anyone have any suggestions?
