Bad boy Warrior Posted March 5, 2005 Share Posted March 5, 2005 I installed ISA on my server. Its blocking a port (or ports) which gives me the following problem - When users logon on it takes about 10 minutes when i ping my server i get an error 65 - searched for error 65 (event viewer give error code 1054 which tells me DNS is not setup properly - but it is, only had this problem after installing IAS) and tried to configure it but it doesnt work - does anyone know which services and ports i require to have open or give access tothx Link to comment Share on other sites More sharing options...
tguy Posted March 15, 2005 Share Posted March 15, 2005 You could start by looking here:http://www.microsoft.com/resources/documen...fc_por_SIMW.aspIf it is only DNS that you are seeking port info. for, it is port 53, TCP and UDP.Other ports are listed in the documentation. ISA is doing what it is designed to do. By nature, most all of today's firewalls are configured to fail closed. You will need to create rules in ISA to allow traffic between various servers or networks based upon the ports required for the applications therein to function correctly.Hope this helps.
