I have double checked my forward and reverse entries and all appears correct. Can somebody give me a clue?? what domains are hosted on ns1.helpfulhome.com that are experiencing these issues? Off the top, the nameservers for .com ( [a-m].gtld-server.net ) are carrying the following NS records for helpfulhome.com: hadrian:~ dig @a.gtld-servers.net ns helpfulhome.com ; DiG 9.2.2 @a.gtld-servers.net ns helpfulhome.com ;; global options: printcmd ;; Got answer: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 53705 ;; flags: qr rd; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 2 ;; QUESTION SECTION: ;helpfulhome.com. IN NS ;; ANSWER SECTION: helpfulhome.com.172800 IN NS ns1.helpfulhome.com. helpfulhome.com.172800 IN NS birch.helpfulhome.com. ;; ADDITIONAL SECTION: ns1.helpfulhome.com.172800 IN A 67.100.249.74 birch.helpfulhome.com. 172800 IN A 67.100.249.74 This means that The Internet is expecting to find information about hosts in the helpfulhome.com domain at EITHER ns1.helpfulhome.com OR birch.helpfulhome.com. But the additional information section indicates that ns1. and birch. are the same machine. I assume this was to remove ns1.lightwaveaccess.net as an NS for helpfulhome.com because it was behaving peculiarly? At any rate, there is no problem having ns1.helpfulhome.com being the primary master for helpfulhome.com since the gtld-servers all carry the necessary glue records. If you need secondary DNS let me know, and get me the list of domains. I'd be happy to accomodate you. madmac [EMAIL PROTECTED] [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Hmm... whois tells me that ns1.lightwaveaccess.net is also an authoritative nameserver for you. At first, I dug at it and came up with the address for ns1.helpfulhome.com successfully. A minute or so later, I got a temporary lookup error. So part of it could be that your secondary DNS is having issues. But ns1.helpfulhome.com was also found at a GTLD server, so lacking a working secondary shouldn't be that disruptive. However, I notice that your NS listings put ns1.lightwaveaccess.net ahead of ns1.helpfulhome.com - the reverse of your whois listings. That might be a problem, but I'm not really certain. If you want, post or mail me some of the domains you host and I can try some MX lookups. That might reveal some more details. -- Todd Pytel Signature attached PGP Key ID 77B1C00C pgp0.pgp Description: PGP signature

Whois says that both HH and LWA are nameservers, but dig shows HH as the sole authority for LWA. I'm not enough of a DNS expert to really trace through this, but it seems to me that there's way too much circularity here. At the least, I think you want each domain's NS to list itself as the primary NS. -- Todd Pytel Signature attached PGP Key ID 77B1C00C pgp0.pgp Description: PGP signature

I am also not a DNS expert, but I was under the impression that you're not supposed to list yourself as your primary NS, as it causes problems if you need to update your own records or go offline. Maybe I'm wrong though. IIRC when I ran DNS services in the past, I listed a friend's machine as my primary DNS, and he was set up to suck from my server periodically. That way, I could tell him to update the IP address if it changed, and all worked smoothly. Whether that was the right way to do things, I'm not sure. -- monique Unless you need to share ultra-sensitive super-spy stuff with me, please don't email me directly.
