If found the main "road block" or "bottleneck" that we were experiencing with DNS services, just not sure why we didn't see these issues years before.
We were directed years ago to NOT setup "Forwarders" in DNS, and instead rely totally on Root Hints if our DNS could not resolve, it's been that way for multiple years. However, once we added our ISP's DNS resolvers as "Forwarder" we immediately restored DNS performance. Could something happened over last weekend to limit use of Root Hints? -----Original Message----- From: Kennedy, Jim [mailto:[email protected]] Sent: Thursday, January 24, 2013 9:26 AM To: NT System Admin Issues Subject: RE: DNS concerns - Server 2003 R2 SP2 Domain Controllers I still wonder why just this past weekend it hit you.

I've noticed that Cisco's "fixup" features tend to break things. -- Ben ~ 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 ~ 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 ~ 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 ~ 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 ~ 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
