If installed in .htaccess, that code will cause an 'infinite' loop, repeatedly rewriting nogtb.php to itself until the server gives up. Fix for use in .htaccess:

RewriteEngine on
#
RewriteCond %{HTTP_USER_AGENT} GoogleToolbar [NC]
RewriteCond %{REQUEST_URI} !^/nogtb\.php$
RewriteRule ^ /nogtb.php [L]

or in more-compact form

RewriteEngine on
#
RewriteCond %{HTTP_USER_AGENT} GoogleToolbar [NC]
RewriteRule !^nogtb\.php$ /nogtb.php [L]

I disagree with telling your visitors what they can and cannot use on their own computers -- It seems a bit presumptuous if they're a potential customer. But if you're going to do it, at least don't put your server through an unnecessary workout while doing so.
