Hi Phil, Do you have WINS set up on these PC and can you ping the mail server by it's NetBios name (NOT the FQDN). Another remote possibility is a typo in the LMHOSTS file. A ping by NetBios name will show this too. If no WINS is configured a typo in the DNS search suffix can do this also. Another thing to check is if the intermediate routers and hubs are blocking the WINS UDP packets. I have an old laptop that I keep W98 and an e-mail client on to show the network folks the 'result' of seemingly low impact router 'tweeks' such as this.
Hope that helps, Michael O'Toole Messaging Engineer ----- Original Message ----- From: "Phil Sheldon" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, February 22, 2002 8:48 PM Subject: Redhat firewall problem > Hi, > > I have a problem with a Redhat firewall using the Monmothas firewall script. > On my internal network I have several dual boot machines.
