DNS resolution
I have seen scenarios where I use RDP to access a computer, but after accessing the computer and run Hostname command I see different hostname than the one I used to RDP to.
for instance, I open up RDP window, and type Computer1 , It will prompt me for domain user and password, I type domain credentials and login. when I am in I open Command line window, type hostname command it will give me computer2.
after doing some research, I found out it is Windows cluster with 2 nodes. but I still do not understand how this is tied up together.
Computer1 has IP= 10.40.9.158
I check I P configuration and saw this:

This is fine too. You can have virtual IP addresses in a cluster. Odds are that the IP address assigned to Computer1 is a cluster resource that shifts to whatever server is active.
