Creating Active Directory on an EC2 box
- by Chiggins
So I have Active Directory set up on a Windows Server 2008 Amazon EC2 server. Its set up correctly I think, I never got any errors with it. Just to test that I got it all set up correctly, I have a Windows 7 Professional virtual machine set up on my network to join to AD. I set the VM to use the Active Directory box as its DNS server. I type in my domain to join it, but I get the following error:
DNS was successfully queried for the service location (SRV) resource record used to locate a domain controller for domain "ad.win.chigs.me":
The query was for the SRV record for _ldap._tcp.dc._msdcs.ad.win.chigs.me
The following domain controllers were identified by the query:
ip-0af92ac4.ad.win.chigs.me
However no domain controllers could be contacted.
Common causes of this error include:
- Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses.
- Domain controllers registered in DNS are not connected to the network or are not running.
It seems that I can talk to Active Directory, but when I'm trying to contact the Domain Controller, its giving a private IP to connect to, at least thats what I can make out of it. Here are some nslookup results.
> win.chigs.me
Server: ec2-184-73-35-150.compute-1.amazonaws.com
Address: 184.73.35.150

Server: ec2-184-73-35-150.compute-1.amazonaws.com
Address: 184.73.35.150
Name: ad.win.chigs.me
Address: 10.249.42.196
win.chigs.me and ad.win.chigs.me are CNAME's pointing to my EC2 box. Any idea what I need to do so that I can join my virtual machine to the EC2 Active Directory set up I have?
Thanks!
