Hi, I'm hoping someone can help me out here.
Prior to this upgrade everything work just fine.
We recently upgraded to a domain from a workgroup. Our domain controller does our AD, DNS and DHCP. We are running ESXi with two Win 2008 R2 server. One as our DC and the other as a file server and backup DNS.
Our setup is pretty simple. We have a line from our DSL modem to an unmanaged store bought switch to our server. All the computers and devices are correctly directly to the switch.
The issue we are experiencing is bout once a day all of our computers aside from the server loose connection with our external webmail. To get it working we have to manually restart the DNS services under services on the server. Sometimes, we also lose complete connection to the internet.
We have replace the modem twice and also the switch. We think it's the DNS causing the issue but unsure how to fix it.
Any help would be appreciated.
