Bind Domain Expiration Problem

[Kal Feher]

So we are all clear about your DNS setup can you include your configuration?

Some questions that may help:

1.Is this a secondary? ie are you trying to do zone transfers from the
authorative name servers?

2.Are your servers cacheing only if you answered no above?

3. Do you have any network issues between your name servers and the primary
for pipelink.com.pk?
