DNS added but not working

[NebuchadnezzarNet]

Hi,
I have created a primary zone at HE for one of my domains, but when i query the dns servers nsX.he.net for any of the records i just created I'm getting a NX :(

Have I missed something obvious, ie. do I have to do something else to enable that domain in your DNS system?

Please provide detailed information, like domain name etc.
