Those are Level 3's full-service resolvers. Unless you're a Level 3 customer, you shouldn't be tying your corporate network infrastructure to those resolvers. They're easy to remember and thus useful for trouble-shooting, but using them in production is inappropriate. It means you're potentially traversing a potentially large part of the Internet with UDP DNS traffic. It also means you're depending on a public service which could go wonky or shut you off at any time. Forwarders should be fast, local, and reliable. Your local ISP's nameservers *may* meet that criteria -- or may not. Since you're having DNS trouble, remove the forwarders and see what happens. Eliminate the obvious potential problem. Even if you are a Level 3 customer, I'd take the forwarders out to see if the trouble goes away. -- 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
