One thing I failed to mention is a major factor in getting rid of the Bluecat devices. The devices had a strong tendency to lockup and or stop accepting requests during periods of high usage. Since the devices could not be pinged or gotten into by http/https or telnet, an emergency change request had to be done. Once it went thru the 3 levels of change control, someone had to call the data center to have the devices powered off and back on.
Because of the many hundreds of zones and because they were standard zones (not AD Integrated) it took almost one month of effort to get off those devices. There was no command or utility to get multiple zone transfers so it was one zone at a time. I also remember something about it wouldn’t transfer all the records in a zone because of the way the DNS records were handled internally and the records had to be manually edited. Sorry, not the DNS records themselves, the zone files that were created by the Bluecats. They were not a standard zone file and Windows couldn’t (wouldn’t) import them so the zone files had to be manually edited. Cricket Liu would have been cursing those Bluecat zones. Overall it was a major royal PITA and they were (are) glad to be off those devices. The customer has had zero issues since moving to AD Integrated DNS zones and Windows DHCP. And I think the Windows team is now making the network infrastructure team go through change control every time they need something done in DHCP or DNS (payback is hell you know).

Any time a DNS record or DHCP reservation was needed, a change control form had to be submitted and go thru three layers of review processes and then wait for a scheduled monthly maintenance window. When you are implementing Citrix PVS, that is a burdensome process.

Just curious as to why the switch to appliance based DHCP from Windows ? ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
