Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm trying to teach myself Active Directory using the self-paced training kit 70-640 unfortunately my networking and System Administration skills are quite poor and I'm having trouble with Chapter 1 / Lesson 2 / Exercise 2 !

I created 1 virtual machine in Virtual Box "SERVER01", this is the Windows Server 2008R2 domain controller for the contoso.com domain

I created a 2nd virtual machine,"SERVER02", which is Windows Server 2008R2 core. However when I try to join the domain using

netdom join %computername% /domain:contoso.com

it says "the specified domain does not exist or cannot be contacted".

Both virtual machines have a single network adapter attached to a internal network.

For what it's worth I can ping the Server01 from Server02.

SERVER01
IP: 10.0.0.11
Subnet Mask: 255.255.255.0
Default Gateway: 10.0.0.1
DNS Servers: ::1
DNS Servers: 127.0.0.1

SERVER02
IP: 10.0.0.12
Subnet Mask: 255.255.255.0
Default Gateway: 10.0.0.1
DNS Servers: fec0:0:0:ffff::1%1 (confused about this!?)
DNS Servers: fec0:0:0:ffff::2%1
DNS Servers: fec0:0:0:ffff::3%1

Also in the network settings of virtual box, what is the significance of promiscuous mode?

Thanks for any help or advice.

Computers joining domain should have first dns server as server01 (10.0.0.11) otherwise they cannot determine DC for a domain.

Thanks. I suspected it might be something to do with the DNS. –  Antonio2011a Sep 3 '12 at 6:00

This is partially incorrect. Computers joining a domain OR IN A DOMAIN should ONLY HAVE AD DNS Servers listed - NO OTHER DNS SERVER SHOULD BE SPECIFIED - doing so can cause sporadic login delays and problems finding network resources. Add ISP/other DNS servers as Forwards if you like in the Windows DNS server, but that shouldn't be necessary as Windows can handle all DNS tasks needed. –  Multiverse IT Sep 3 '12 at 6:30
    
@MultiverseIT Thanks for the clarification ! –  Antonio2011a Sep 3 '12 at 8:42
