active directory, DNS

I found 1 windows server name server@xyz.com  in vcenter VMware 5.5, I can ping the server , not by host name but by ip address

I can also when type the FQDN in RDP I see it ask log in name  but no body cant log in as we cannot find the server in entire directory when we do research

so is the server deleted or is it some where because we can ping the server.

one expert said that it has DNS suffix and may not join domain but I am not sure.

how can I check

Okay so in vmware you have a server that is running correct?

From vmware can you console onto the server?

It's possible the server just isn't joined to the domain and there isn't a DNS record for it which is why the name wouldn't be found.

I would console onto the server, see what it's doing and if all else fails do a scream test of shut it down (do not delete it) and see if anyone says something isn't working. If after 30 days then export the vm and delete it.

but the server is pinging through ip on domain workstation  so it has PTR record

on VM it clearly says servername@domain.com

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

VMware Tools just reports what it finds in TCP/IP information in networking!

log onto the Windows Server in question, and check it's IP Address.

then check the IP Address in DNS, and see if it's registered.

You just might have a server which does not have a A Name record in DNS

(not a VMware vSphere issue!)

we cant log into the server , no body from AD team cant loginthrough rdp or Cannot find the host itself in AD

we can only ping the server ip, which we get reply we want to know whether it is in stale condition or somewhere or not?

if we don't find the ip ADDRESS IN DNS what conclusion we can draw

VMware Tools is running ?

and it shows and IP Address ?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
So if it exists in the Inventory, you can view the console ?

You have the ability to power off, power on, disconnect from network ? and based on those previous commands, can check if the IP Address your are pinging is this Device (server)?

and if you can get to the console, you can login....

so u mean power off the vm and then try to ping the same vm, so what inference we are drawing

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
You don't have to power off the VM.

But you can check if this is the device you are pinging, by disconnecting from network.

and if you have access to console, you can access the VM.

You should be able to then work out from networking in the VM, DNS.... why you cannot access via RDP etc

it may not be available...

what are you trying to prove, where the VM is, what it does, why you cannot ping by DNS name ?

You state is it deleted, it's clearly not deleted, it its powered on and responding to pings ?

we want this server in question for snmp monitoring but we cant find the server, so our boss wants to know is it active, stale or gone already

from system which w e cant determine

so after discoonecting  it doesn't ping and reconnecting it pings that means server is there somewhere in that domain?

the question is we cant find the ip in dns and server is pinging what conclusion we can draw

So tell your boss...

Some idiot, didn't allocate and create a record for it in DNS!

Some idiot, didn't configure the server correctly.

Some idiot, didn't create any documentation for it.

Pick one of the above...

how will we know it is in use or not

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Can you open a console to the VM ?

What OS is running on it ?

Ask the Administrator which configured and created the server for the password ?

Maybe ask your boss for the password ?

how will we know it is in use or not

Logon? check documentation ? check server name, is there a clue in the name ?

we see ip in PTR records but cannot find the host name

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
why do you keep referring to DNS?

Is a PTR records or Hostname, going to tell you what is running on it ?

how is that going to help you with the above questions ?

LOGON TO THE MACHINE MAN, and check it!

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Please logon to the VM, and check it over...

what's installed in the VM, is it connected to domain, is networking connected and configured correctly

does it have any shares, any users connected to it, RDP enabled and configured....

and then correct it and start using it.

WHAT is in a deleted STATE?

The VM is powered on and alive, and working ?

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
What OS is the VM ?

and you cannot login, and don't know how ?

You've got three options then :-

1. Power OFF the VM, DELETE IT. Report to BOSS it's GONE and DELETED, and cannot be used!

2. Login and Check. Report to BOSS. We don't know how to login to the VM we have found.

3. You can Ask, Would you like help logging into the VM ?

Does the IP this server has set as a static ip? If it is not, the likely explanation to your situation if the VM server is continually running is that DNS fo figured scavenging deletes theA record. A PTR is not what is used to locate a server on direct connection attempt.
A PTR record reflects the registration of the IP by a host.
An A record is the registration of the server's host record to the IP it has.

On the server, in elevated command run:
Ipconfig /registerdns
And see if your record shows up in the DNS, noting the name server records on this server are those to which these requests will be sent.

Commonly, manually adding DNS records to DNS servers on the domain will be permanent and not subject to the scavenging compared to records registered by the network adapter...
