DNS reolution case sensativity.....

I understand that DNS is case insensitive.  However, we have an application that requires the DNS resolution to either be all uppercase or all lower case and not change.  If it changes the application breaks.  Yeah, I know. 

So, is there a way to force the DNS server or DNS client to convert/resolve any DNS request results in a certain case.  So, if the client tries to resolve Hello.YES.com and the client requires that to be all lower case, can we force the client or DNS server to readthe results in ONLY lower case (i.e. hello.yes.com)?

Thanks,

Dave
