DNS problems Heeeelp :)

[Luca]

Hi,

alright, picture this:

I have a server with PLESK running with its own nameserver and 2 IP's. A few domains run on there.

I setup a new server which has 1 IP, nothing more. (Debian Etch)

I install ispcp-omega, so far so good.

On the PLESK server I create:

webserver2.mydomain.com (A) IPofISPCPomegaServer
admin.webserver2.mydomain.com (A) IPofISPCPomegaServer

In ISPCP I create the user with domain webserver2.mydomain.com.

--I can now access the ispcp server with that but now

ns1.webserver2.mydomain.com (A) IPofISPCPomegaServer
webserver2.mydomain.com (NS) ns1.webserver2.mydomain.com

If I know create myotherdomain.com in ISPCP, and in the provider control panel of the domain I place "ns1.webserver2.mydomain.com" as "use my own dns" I get "Nameserver invalid!"

What am I doing wrong here?
