I'm running Exchange 2010 and my own DNS server ( I know it's not recommended but I've been doing it fine for the past few years).
Just recently I've been having some odd error messages in my queues. I've already posted a question here about that so I'm not going to go into that again.( http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_28583497.html
But something I noticed is that the timestamp on my DNS entries for my two mail servers (.72 and .73) has changed recently to a recent date, just about the same date I started having trouble.
My question is this, what could cause those timestamps to change? I did not change them. Would some internal process cause them to change?
