DNS resolution
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:

<<You should be able to use cluster administrator to view the details and find the virtual server names. >>>
where can I find that ?
I have windows 2003 cluster

I mean I open up Cluster Administrator, there are 2 node names and the one that show up on the top of cluster Administrator left pane.
ComputerX (on the top)
computer2 (node1)
computer3 (Node2)
however when I used RDP I used computer1
and when logged in and typed hostname command ,it shows computer2 (it got to be the Active node)
to my understanding:
ComputerX is the virtual name of the cluster
computer 2 is the active node
computer3 is another active or passive node (I am not sure I need to find out)
But computer1 , You would think it might have DNS name pointing to computerX, but I cannot find that info in DNS

computer2 and computer3 the cluster name is ComputerX
I am not sure how the computer1 name got there
