vCenter 5.1 Change DNS
Posted on 2014-04-14
Our vCenter 5.1 is installed on a Windows Server 2008 R2 VM in our environment. It currently has 2 DNS entries under the NIC that need to be changed. The current DNS entries are servers that were decommissioned. Anything pointing to the old DNS servers are rerouted to the new DNS servers. So we have to change these DNS entries as soon as possible to the correct entries.
My question is how easy is it to be changed? Do I just have to change the 2 DNS entries on the NIC to point to the server DNS entries? What will happen once I change over to the new DNS entries, will things go down, get disconnected, etc...?
