comment Remote Desktop Connection - Connection Failed
I don't quite understand. Are you saying that if you use the IP and not the name of your machine, it works all the time? If that's the case, then you are likely dealing with a DNS problem, and not a network one. My guess would be that there are different search lists set up on different machines.

The next time it fails, you can filter for your destination address with tcpdump like Borys suggested.

comment Postfix: Connect; Immediate Disconnect
By default, postfix should log all of the transactions involved in the processing of the email. If it was resulting in a 421, that should be glaringly obvious in the mail log.

wow, if those two resources don't answer your shell scripting question, I'm not sure I even want to know what you're trying to do

comment Branch Office RDP sessions disconnecting
Kyle is correct, although I think you've already isolated the problem to your network connection. If the TS servers have other users connected from different locations that are not timed out, then it's not the servers at fault. Site-site VPN is completely different than a regular TCP or UDP connection, so that does not serve to exhonerate your firewall/switch. I'm not familiar with Fortinett, but I would check your documentation for some default timeout values that would be incompatible with long-running TCP connections, especially if you're running PAT.

comment Basic dns question: www vs mail
correct, if incoming mail is currently landing on the server at the thedomain.com resolution, then it's probably got the requisite A & MX records.

comment What i need to read in order to configure PowerDNS?
Wikipedia is a good start: en.wikipedia.org/wiki/Domain_Name_System Also, it's a little dry, but the DNS & Bind O'Reilly book is a pretty solid resource.
