Not sure if you are aware of this or not but Windows Server 2003 (are you running that?) is configured for EDNS by default. The Pix OS is incompatible with that out of the box. The newer pix os version have a dns fixup protocol setting to allow the longer DNS packets through. Just thought you should be aware if this in case you are not. It basically causes random DNS query failures and can be more than a little frustrating to troubleshoot unless you know it's there. You need to set the maximum packet length. Syntax: "fixup protocol dns maximum-length 1500".

Subject: [IMail Forum] DNS Service Down

I just installed a new PIX501 on our server.  During the configuration - I came across the IMAIL Monitor Service ( web based ).  Really cool set up.  However, after logging in I noticed our DNS service is DOWN - WSAENOTCONN .
 
Why is this?  Our box is w2K3 and has been working great.  This box not only runs IMAIL ( with about 100 domains), but also our web server ( with about 300 + sites ). 
 
Everything appears to be working correctly on our box - why does the web based IMAIL Monitor service show our DNS service as being down?  What exactly does this mean?
 
Thanks!
