Additional Domain Controller IP Address

[computerMe]

What is an ideal way in putting IP address for additonal DCs? Static or Dynamic?.

Because when I tried to put a static IP address before doing the installation for an additional DC the domain controller I got this error the cannot be dectected. But when I changed the IP address to automatic/dynamic the domain was detected and the AD installation process continued...

Any suggestion is very much appreciated.. THANKS

It sounds like the IP configuration you used may be incorrect. You should never have a DC with a dynamic IP.

Thanks, djtech2k

This is my configuration...

Here is my DC info
IP Addess : 100. 0. 0. 10
Subnet mask : 255.255.255. 0
default gateway : my router ip
Prep DNS Svr : 100. 0. 0. 10

my additional DC
IP Addess : 100. 0. 0. 11
Subnet mask : 255.255.255. 0
default gateway : my router ip
Prep DNS Svr : 100. 0. 0. 11

Any correction pls..thanks..

When you put it on the network with this config, can you ping anything? Does it have 2 NIC's?

 

[computerMe]

1 NIC each computer the DC and the Additional DC. I can ping it if I will ping the computer name, but if I will ping the domain name the error is this could not find host.

 

[djtech2k]

Well thats a DNS issue then. Are you pinging the FQDN or just the DN?

 

[computerMe]

I'm pinging the NetBIOS / DN... same error. maybe you'r right djtech2k because I'd check in my DNSMGMT and found out that the additional DC computer did't appears .

 

[djtech2k]

If you are using integrated DNS and everything is setup properly, then from any domain member machine you should be able to ping your FQDN and get a result. For example, if your domain is domain.local, then try to ping domain.local.

As for your server not being visible in DNS, try running this from that server:

ipconfig /registerdns

I already found the problem djtech2k. It was only the DNS configuration IP conflict.

Thank you very much for the help.. you are the MAN!. ..
