mojo31, indeed it cares, to the point that I mention above. If a site doesn't get rebooted during certain period of time (usually months) and eventually ip conflicts start to flourish (eg. mass migration of PC workstations at site and high DHCP release/renew traffic) then it might eventually...

I had been assuming that when a router (Cisco) detects a DHCP address conflict, it would at some point reassign the address. Unfortunately, I've discovered that that's wrong and if an address conflict is detected, the address is removed from the pool, and the address will not be assigned until...

Two yrs ago my team and I were appointed to come with a plan to migrate certain service from one platform to another in around 400 locations globally and within 2 yrs. We worked on schedules, costs and support plans. The technology was properly tested and it has show to be mature, stable and...

EnemyAce That error doesn't necessarily mean that someone on purpose is trying to modify your DNS files. That internal IP (individual or device) might be running some kind of DNS deamon without even knowing. I'd suggest you traced it back if you can and HR allows and take a look into that...

chosen1 Create a sub-zone in A&B for "*.session.rservices.com" and set them as forwarders to C. That way whenever you have a client in A&B's DNS region requesting "*.session.rservices.com" resolution, A&B will forward that query to C regardless. Good luck! Jose Luis Martin Cenjor, CCNA, CCNP HP...

Me and several other colleagues out here got exactly the same question. Appreciate help Jose Luis Martin Cenjor, CCNA, CCNP HP Global Technology Solutions www.hp.com

Is your ftp site within the same IP range as your PC? I suspect it might be something with your FTP client and timeout settings in it. If the ftp site is in a different range and a router in between, you might want to check any applied access-list in it denying ftp traffic. Let us know ... Jose...

If dynamic updates is what is failing here, you might want to check the below link to make sure you've setup the appropriate access-list and allow-update directives in your Name Servers. I'm using UNIX as my name servers and allow AD to update them dynamically via a named access-list at the...

Glen, I am currently setting up something similar to what chmilz describes. What you mention is for the DNS query/reply flow. But to allow zone xfers through the firewall ... should any specific TCP port be opened? Thanks a lot! Jose Luis Martin Cenjor, CCNA, CCNP HP Global Technology Solutions...

Thanks Glen, that's very helpful! Jose Luis Martin Cenjor, CCNA, CCNP HP Global Technology Solutions www.hp.com

Any help out there? Not know Win2K/WinNT4 appropriate DNS instructions to the detail. Jose Luis Martin Cenjor, CCNA, CCNP HP Global Technology Solutions www.hp.com

What platform are you running DNS on? Jose Luis Martin Cenjor, CCNA, CCNP HP Global Technology Solutions www.hp.com

1665, reverse lookups are almost as important as the ones that you mention (widely known as forward lookups). Many applications rely on reverse lookups to figure out the name behind a given IP. If you are setting up your DNS manually then this tasks of creating the reverse lookup db files will...

Not sure I fully understand, but godaddy.com will resolve your domain name to external clients sending DNS queries for it and that's how they will point to your server ... Does this make any sense??? Jose Luis Martin Cenjor, CCNA, CCNP HP Global Technology Solutions www.hp.com

colophon, I agree with Glenn, try also to get some network info (traces, ip accounting, sniffer) from the Layer 3 devices in between, you might catch a flow or the TCP info you need from the troubled device within the flows in those routing devices? Have tried reinstalling TCP/IP in the device...
