GconfTool-2 Always open in browser window

[techfour]

How can I enable this Edit->Preferences->Behavior and then select (check) Always open in browser windows setting with gconftool-2 ??

I tried the following commands and none of them are putting a check mark on the "Always open in browser window"

gconftool-2 --config-source=/home/user1/.gconf/apps/nautilus/preferences/always_use_browser true
gconftool-2 --config-source=xml::/etc/gconf -t bool -s /apps/nautilus/preferences/always_use_browser true
gconftool-2 --config-source=xml::/home/user1/.gconf -t bool -s /apps/nautilus/preferences/always_use_browser true
gconftool-2 --config-source=xml::/home/user1/.gconf --recursive-list / | grep browser
gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults/ --type boolean --set /apps/nautilus/preferences/always_use_browser true

I need to do this on hundreds of Centos servers.

Thanks in advanced.

Gconftool is not a CentOS program. Where did you get it?
Oops. I searched for gconftool instead of gconftool-2..
Gconftool-2 is in base.
