Doug, thanks for the comments. The "problem" would seem to be an issue with the way that "Microsoft DNS" server interprets the result. I already have this as an open Microsoft support incident, but am trying (by asking on the BIND support forums in the hope of finding some DNS-experts) to find some "official information to reinforce my opinion that "BIND is operating 'CORRECTLY'", and to find the exact RFC text (or otherwise) that basically says the follwing: * Here is the spec, here is confirmination that the "original record from primary-dns.co.uk" is valid, and here is an RFC saying how this should be interpreted. So, I'm really asking for assistance in troubleshooting, rather than reporting a problem. It is no good me just saying to Microsoft "I think you are wrong", but if I can find a "SPECIFIC" problem and come up with a statement like "Here is EXACTLY where the Microsoft-implemention does NOT adhere to section XXX of RFC yyy" then I'm more likely to get them to implement a hotfix. --- Regards, Steven Wilmot Director Data Utilities Ltd _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
