Hi,
I have a problem with isa 2006 firewall client on windows 7 joined to domain , I can browse websites with webproxy but I cannot connect to any pop3 and smtp mailservers when using pop3 dns name on outlook, so if I add the full name of mail.something.com, it does not work with (name cannot be resolved), it works when adding ip address, also if I try to access ftp servers on internet it does not work.
This only happens with windows 7 computers windows xp works correctly with firewall client.
If secure nat client is used on windows 7 they work (but I need to authenticate users by name).
I have searched many forums but cannot find a solution.
I have rule in isa server that allows http,https,ftp,ping,smtp,pop, even the rule that applies to me which have all outbound ports open had the same problem.
Thanks in advance.
