The IP Addresses in the Summary are reported from VMware Tools, IP Addresses it has found in the OS.

So I would check using IPCONFIG in the Guest OS, and confirm these IP Addresses are correct.

BUT, it does not really make any differences because these network interfaces will be re-created/lost in the new VM in Hyper-V

e.g. the virtual hardware is different between VMware and Hyper-V, so new network interfaces will be re-created, and you will have to ensure these are correct for the VM.

> VMWare it shows me two different ip address in the summary

i prefer seeing a screenshot to determine and confirm what they are.

as Andrew mentioned above, one of them should be the IP address of guest OS. how about the other?

BTW, do you have two NICs assigned to the VM?

As I said, question is redundant, after the V2V! (conversion!)

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

You would have to ask the person who set it up, why they added two separate IP Addresses!

the network interface has been configured with two IP Addresses.

Check which IP Address is used in your organisation, e.g. check DNS

if you ping the name of your Exchange Server which is returned ?

does not really tell me anything.

The guy that was here was fired, i took over and was thrown in this as it is, i have never seen that you need two ip's unless you have different domains, and even then i am really not sure, when i ping i get the .13 address using the name i get a reply back, when i also ping .15 manually directly i get a reply back but this time i was not using the server name.

RDP works using both IP's so they are both pointing to the server

if you address the server by IP of course RDP will answer!

BUT, if you ping <exchange server name> what IP answers, e.g. what's the A Record in the DNS ?

2.13 - if this is the one in DNS, then that's the one you are using and the other was setup for whatever, backdoor entry, for your guy to snoop after he left!

or

2.15 ?

Look in DNS ?

Found it is been used for a relay, the printers send information via this relay to the exchange server.

So when you re-create the VM, in Hyper-V, you will need to ensure that the network information is the same as currently!
