Hi all,
I have a ESXi5 box (Dell PE 2950) running Win2008 as a DC and DNS server as well as a ClearOS Pro 5.0 appliances running. They have been running fine for the the last year with no problems and now both appliances lose internet connectivity within a couple minutes of starting. From within the consoles of each appliance I can ping around our local network with no problem and resolve host names internally but they can not reach anything outside the network for some reason nor resolve names. Every time I reboot, internet connectivity is there for a couple of minutes then disappears. Workstations, if set to use our isp's DNS servers connect just fine to the internet, if I set them to use the Win2008 DNS, they can connect for the first few minutes but once the DNS server loses connectivity, workstation connections are lost.
What is up with this.
This is driving me nuts....
Thanks
Jeff
