We are trying to configure F5 to do load balancing on 4 sub domains similar to this article...

http://support.f5.com/kb/en-us/solutions/public/0000/200/sol277.html

For Example

prod.wip.example.com. NS F5NS1.example.com.
prod.wip.example.com. NS F5NS2.example.com.
test.wip.example.com. NS F5NS1.example.com.
test.wip.example.com. NS F5NS2.example.com.

Then we want to make cnames instead of delegating individual sub-domains, e.g.

myapp.example.com CNAME prod.wip.example.com

Microsoft DNS gives an error when I attempt to make the CNAME...

dnscmd ns1 /recordadd example.com myapp CNAME myapp.prod.wip.example.com.

Command failed: DNS_ERROR_NOT_ALLOWED_UNDER_DELEGATION 9563 (0000255b)

The error makes perfect sense, but does anyone know of a way around it? Or are my NS records incorrect for this setup?

Thank you, -Steve
