Our DNS > servers are Windows 2000. When you say DNS-53, do you mean UDP or TCP? You need to allow both in order for DNS to function properly.

It may be these larger requests that are failing. -Don ================================================= To set vacation, Out Of Office, or away messages, send an email to [email protected] in the BODY of the email add: set fw-1-mailinglist nomail ================================================= To unsubscribe from this mailing list, please see the instructions at http://www.checkpoint.com/services/mailing.html ================================================= If you have any questions on how to change your subscription options, email [email protected] =================================================
