I thought this was just a random issue but this has happened to three clients now one using clearos 5.2 the other two using clearos 6.5
When pinging the server name it's not the internal IP address it's the public one.
I've done release, flushdns, renew still external. I've deleted the dhcp entry in clearos and got a new IP address still same issue. It doesn't seem like clearos has any problems but I've ended up manually adding in the host file the internal IP address for the server on that machine.
It's not happening to all computers in the office just one particular one for each site.
Has anyone else encountered this problem before and knows how to resolve it?
