help with local security settings

Hi all,
I hope someone can help me out on figuring this issue out on my windows server 2003 r2. Im trying to "add user or group" on the "adjust memory quotas for process" policy in my local security settings and the "add user or group" button is greyed out. I need to add "network services" to the list but I'm unable to do so because of this reason. I am also logged in as administrator, and I'm stumped on which group policy is prohibiting me from allowing me to access this setting. Any advice would be much appreciated.
Thanks!
