Event ID 800, DNS, A record for primary serverin zone's SOA record not available.

Hi, I am getting this error on our server and I can't for the life of me think why!
Event Type:      Information
Event Source:      DNS
Event Category:      None
Event ID:      800
Date:            26/03/2004
Time:            3:18:36 p.m.
User:            N/A
Computer:      SERVER
Description:
The zone Whakatohea.local is configured to accept updates but the A record for the primary server in the zone's SOA record is not available on this DNS server. This may indicate a configuration problem. If the address of the primary server for the zone cannot  be resolved DNS clients will be unable to locate a server to accept updates for this zone. This will cause DNS clients to be unable to perform DNS updates.

The server is on dial up internet and I think that what is happening is that if it is disconnected from the internet, all the printers go of line on the workstations which we access via terminal server on the server, the server is trying to forward dns requests to the isp, so when you connect to the internet its all ok.  I'm not sure why it is doing this, forwarders are turned off.
Thanks for ya help!
