As  suggested in previous replies, it looks as though the problem is with
one of the following two possibilites

---- 

1 - The original server-configuration (or response) from "primary-dns.co.uk"
is NOT VALID

If this is the case, could you please help let me know exactly which RFC or
configuration that you believe is not valid.

Note: 'primary-dns.co.uk is owned and maintained by my ISP (aaisp.net.uk),
and I'm fairly certain that they would be quick to implement any
"corrections" if you were able to demonstrate a SPECIFIC bug

----

OR:

2 - The response from 'primary-dns.co.uk' is VALID, but the Microsoft-DNS
server is not interpreting this properly.

If this is the case, then I'm looking for help in identifying exactly which
RFC (or other specification) it is not implementing properly.
