A DNS Server can have more than one namespace so this is not the problem.
What you should check though is what namespaces are already there. Your
writing that you have:
abc.abc.com
which is a subdomain of abc.com and can only exist if the domain abc.com is
there. So you would be trying to create a new namespace for a domain which
already exists.

i see..thanks for your

i want to know is ..now is for example xxx.abc.abc.com is a domain
controller in windows 2003 environment
and xxx.abc.com is in domain in linux environment and hosting linux email .

so if i later change email server to exchange environment , did i need to
creat new DNS for exchange or using exsiting DNS xxx.abc.abc.com to creat
new zone for xxx.abc.com?

thanks

There is no need for a new namespace - use the old one for exchange.
