We have a situation where we seem to be having intermittent issues with web pages not loading up and causing a bit of slowness on an otherwise OK LAN. We have been investigating all things pertaining to this, ie, DNS forwarders, router, even EDSN0 settings (which are off), and we still are having the issue. Lasts 1 to 5 minutes and about the same time(s) of day but not necessarily everyday. Email for the Exchange and the ISP do not go down, just web pages seem to go into limbo.
Its an SBS 2008 network with Exchange, AD, DHCP, DNS, no SharePoint.
So we want to put in a temporary Windows 2008 R2 SP1 server and put a secondary DNS instance on it. We will put a few users on it to test to see if the issues persist. If it works, then we may keep it in place. This is why we don't want to make it a secondary DC, just a secondary DNS.
Can someone please advise on the specific steps entailed with this so that we don't blow things up? I've researched different answers to this, but it's a little confusing.
Your help or experience is greatly appreciated.
