Windows 2008: Cannot access by computer_name

In

Can you copy and paste an example of an nslookup result showing us the
errors or non-resolution you are seeing? That will better help us to help
you. I believe I asked that before, but I did not see a reply. Try the
following:

nslookup
netserver
(please post your results)

netserver.kool.com
(please post your results)

Then try it with the following 'set vc' switch:

nslookup
set vc
netserver
(please post the results)

netserver.kool.com
(please post your results)


Also, is there a firewall rule running on all machines and the DC to stop
pings (ICMP echo) from working, as well as DNS queries (UDP or TCP 53)?

Looking forward to your results. If you have more tests that I didn';t
mention, please post them too!

Thank you,

Ace

 

I demoted to workgroup and re-install the AD & DNS server, I change the Ip to
192.168.0.2 to see it will work or not, it did not.

Here is the NSLOOKUP from Server

C:\>nslookup
Default Server: netsever.kool.com
Address: 192.168.0.2

Server: netsever.kool.com
Address: 192.168.0.2

*** netsever.kool.com can't find netserver: Non-existent domain

You demoted your domain controller? Why?

Try it with:

If that worked, then it's telling me that the search suffix on the machine
you are running this is not kool.com, or it has been changed, or the record
'netserver' does not exist in the DNS zone under the search suffix domain
name the machine you are running this on is set to.

For example, from my own workstation, which has a different search suffix
than my domain, I tried to look up a name called 'bob' on my machine:

Server: london.contoso.com
Address: 192.168.1.40

*** london.contoso.com can't find bob: Non-existent domain

This means that 'bob' does not exist under the zone the search suffix on my
machine is set to, which is 'nwtraders.com.'

However, when I did an nslookup for bob.contoso.com (using the full FQDN),
it gave me a proper response.


Can you post your new ipconfig /all, please?

Thanks,
Ace

 

Read inline please.

Put nslookup in verbose mode and repost the results.

C:\nslookup
