AD without DNS

just had a conversation with another SE and he told me that their AD infrastructure works completely without MS DNS. instead,they have BIND servers.

im pretty skilled with AD,but im having a hard time to understand that their infrastructure works without issues.

1. all DCs are server 2008 R2,but functional level still 2003.
2. all DCS  are "only" DCs,no server has DNS role installed

is this even possible to make it work? i cannot imagine that AD can function properly without any DNS on their servers,but a 3rd party solution. its QIP i,believe.

im wondering what issues are obvious possible when running this?
is a AD upgrade to server 2008 R2 domain-and forest functional mode even possible?

and what happens when server 2012 DCs and member server are getting implemented?

There is a comman problem happens when server 2012 DCs and member server are getting implemented. you gets error "The specified domain either does not exist or could not be contacted".

Check for DNS in this case.......

our environment is scientific and we have about 600 servers: vastly windows servers,but also many linux/unix as well.

so, the expertise is to leave all the way it is and raise domain-and forest functional mode without worrying?
