Hi
We are getting the folowing error message in the dns eventvwr
Event Type: Error
Event Source: DNS
Event Category: None
Event ID: 6527
Date: 08/08/2007
Time: 14:24:11
User: N/A
Computer: EDUCATION-DC2
Description:
Zone xxx.yyy.zzz.gov.uk expired before it could obtain a successful zone
transfer or update from a master server acting as its source for the zone.
The zone has been shut down.

*I have substituted the fqdn*

The zone is appearing on the secondary but has disappeared form the primary
dns server.

Any ideas on may have caused this to happen, no other error messages are
appearing. This has only happened to eexplicit zones and when we resarted the
primary dns server the zones came back in only to be lost after a period of
time

any is appreciated

Chris
