I was rdp'd into an SQL Server today and did a backup before making some changes; so I needed to restore the backup, when suddenly the rdp session disconnected and I thought I saw the purple "restarting" screen just before it did!
Horrified I tried to log back into the machine, and got an error about the protocol.
My localhost system was also out of memory as I was notified of as I pulled up a powersshell prompt to try to connect to it with winrm, so I closed out firefox and then was able to rdp to it again;
But when I went in to look for my backup on the same drive where I saved it; it wasn't there!!!
So I went and got our infrastructure guy who told me that the server I was rdp'd into was part of an sql server cluster and that the other machine had taken over for a machine that was restarted by a vendor when I was on it!!!!
The dns record is connected to "both?" machines or switches to the other machine on a fail over. If you run hostname on them they have different names but the same dns entry will connect you to one or the other depending on what is up and which dns entry it is pointing at.
I ran dig against the dns entry to find out which IP it pointed at, but it only came back with one ip, I was expecting two...what happened there? What changes switches the ip record when the one machine goes down?
