All PCs in our LAN have installed MS Firewall Client in order to access Internet via MS ISA Server.I have created a rule to enable SMTP,POP3 and DNS Query protocol for any MS Firewall Client. I added an email account in Outlook Express of a client PC. I am sure that the pop3 and smtp host domain is no problem.

But when I checked that inbox, OE told me that it couldn't find pop3 and smtp host! I didn't set any DNS Server for this client as I think Firewall Client would forward this DNS Query to MS ISA Server while ISA Server could do this.

Any help or advice? Thanks in advance.

Hi Xadave,

have you already checked the ISA FWlogs for any entries? Maybe that can give you any idea what exactly is happening: DNS problem, access rights, etc...

If DNS lookup is done by ISA, try a nslookup from your ISA server. This should work, otherwise fix your DNS. If I remember well, you should find an entry in your FWlog with a keyword GHBN (Get Host By Name socket call) if the FW client asks ISA todo DNS lookup.

Have also a look at http://www.isaserver.org/authors/harrison/tutoials/isa-clients-part3.htm

Hope this helps,
Stefaan
