Join domain fails from 2008R2 VM in basic networking
Hello,
My test environment (4.0) is in basic network mode and I have one 2008R2
VM running. Aside from Cloudstack, I have one AD+DC+DNS(no dhcp) that I
configure as my zone DNS. If I try to enter my 2008R2 VM to this DC
Domain, it fails saying it could not find the domain.
>From the 2008R2 I can ping the ADDC server but not the domain name.
Nslookup fails and indicates the ip of the Virtual Router. I thought when
Virtual Router resolution fails it should use the zone DNS. (It also fails
with the flag use external dns active after Management Server and Virtual
Router reboot)
Is there any way to make this work or do I have to go to Advance
Networking?
Best Regards,
Sebastien Vandenberghe

Hello,
I finally got it...
If the DC server is configured as DNS 2 the query doesn't work. It has to be the first one or I can't find any working parameters in cloudstack to force the dns to be external. I then script it in my VM template for the first startup.
Do you think it is a CloudStack bug to not allocate the first DNS to the one chooses in the zone?

Hello Kirk,
The DNS configuration is the virtual Router and I added in DNS2 the DC.
I can ping the DS and nslookup returns the good IP for the domain I try to join. I have no security group at all. The error message from windows when I try to join the domain is:
The error was: "No records found for given DNS query."
(error code 0x0000251D DNS_INFO_NO_RECORDS)
The query was for the SRV record for _ldap._tcp.dc._msdcs.cloud.poc
Other machines (not VM in cloudstack) can successfully join the domain.
I definitely think to a virtual router issue. Is there something else I can test?
Thank you,
Best Regards,

Hi, Sebastien. Does the 2008 R2 VM actually have the correct DNS configuration (the DC)? CloudStack might not be assigning the DC as the DNS server for some reason. If the DNS configuration is correct on the VM, check if any DNS query works, and check other connectivity (ping, etc.). If the zone has security groups enabled, make sure there are no rules blocking access to the DC.
Best regards,
Kirk
