Hi - We have three servers: DC, RDS (term server), and Exchange, on a 30 user network. All are Server 2008 R2 Std. All are connected to the internet via a sonciwall tz210 firewall.
The servers were set up recently by a tech who is no longer around. We have intermittent issue where users lose connection to servers and to the internet. One user will lose it, then the next, then the next. A restart of the servers seems to fix the issue for a while.
My question is, how should DNS be configured on each of the three servers?
