Good Morning,
I have a 2012 AlwaysOn \ DB Mirroring environment set up with two nodes. Both have 5 installs of SQL named instances.
The issue we are having is when we patch one server and fail everything over, some of the applications will error. Some of the applications had to have their web.config files updated with host\instance name because it seems to not work with DNS.
Any articles, literature or responses would be appreciated.
Best,
Frank MMA
