Can Windows 2003 DNS mmc connect to Windows 2008 R2 DNS?  I have a mixed environment and I cannot connect to my recently installed 64bit DNS server running 2008 R2.  I tried searching to see if there is a known reason but cannot find any.  Does anyone know why?  I know both DNS serves are running fine.

Yes, it can.

When you attempt to connect to your 2008 DNS instance, what error(s) do you receive?

I found this on a technet question:

In order to use DNSMGMT.MSC to manage DNS on a Windows 2008 R2 server from WinXP/2003, you have to run the following commands on the Windows 2008 R2 DNS server and restart the DNS Server service.


dnscmd.exe /Config /RpcProtocol 7
dnscmd.exe /Config /RpcAuthLevel 0



 RpcProtocol needs to be set to 7 in order to run DNSMGMT from Windows XP/2003/2008 remotely AND to run on Windows 2008 R2 locally.


 To view your current settings, run the following commands.
dnscmd.exe /Info /RpcAuthLevel
dnscmd.exe /Info /RpcProtocol

I get "Cannot contact the DNS server"  and then the standard other responses "dns server may not be running", "network problems". However I can ping the 64 Bit DNS server fine from the 32 bit one, I can query 53 with no problems and from what I can tell, records are transferring.

I'm pretty sure this would fix it but after a little thought and reading I'm not going to downgrade the security policy just so I can remotely manage the 08 DNS.  If I have to make a DNS change I will rdp into the box or until I upgrade my other AD/DNS then this issue will be moot.

thank you!
