Not being there, it hard to guess the problem via an email thread _but_ if NSlookup won't connect to a name server by IP address, that gives me a clear indication that something is up with DNS.  A missing PTR record(s) should have not impact with connecting to the name server with the NSlookup command via IP address.   We just had a situation this week where our NetOps guys decided to upgrade the DNS boxes without letting us know.  There where problems with the upgrades and the NetOps guys did not catch it.  Our exchange servers could no longer route mail.  A lot of folks scratching heads and calls to MS PSS.  A quick check with NSlookup to the nameserver that the servers were using showed the source of the problem.  The server could not enumerate the records for the AD zone....   Diane From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Kingslan Sent: Tuesday, June 10, 2003 7:54 PM To: [EMAIL PROTECTED] Steve, Diane -   I agree that there is clearly something wrong with the DNS.  But, I'm not so sure that this is the indication.  This can also be caused (most likely) by a missing Reverse Lookup.   This was mentioned once before - have you looked into this yet, Steve?   I'm much more concerned with the missing registration for the GUID.   Steve - we (collectively) have made some suggestions.  Have you followed up on:   Checking the registration of the Active Directory Zones in DNS?  You should see 4:   _msdcs _sites _tcp _udp   Do these exist?  If not, go to the DNS applet and right click your domain fanmats.com.  Make sure that you're set for 'Yes' in Allow Dynamic Updates.  Go to Services, then stop and then start 'Netlogon'.  This will force a registration of DNS zones.   Please follow ALL STEPS on this page.  Some have been outlined here time and again by other people, but the steps need to be followed.   http://www.microsoft.com/windows2000/dns/tshoot/dns_tshoot2A.asp   This is a common problem.  DNS can be a real bear, but AD will NOT WORK without it.  You have to get this right, as you're finding.   And, if you want to bring back BOTH netdiag and dcdiag results (successful or not - many time successful results tell me a lot) please run them as follows:   dcdiag /fix   netdiag /fix   dcdiag /v /f:dcdiag.log   netdiag /debug /l  (this will automatically create a netdiag.log)   Good luck - we'll be waiting to here what you have found.   Rick Kingslan  MCSE, MCSA, MCT Microsoft MVP - Active Directory Associate Expert Expert Zone - www.microsoft.com/windowsxp/expertzone         From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Diane Ayers Sent: Tuesday, June 10, 2003 8:57 PM To: [EMAIL PROTECTED] >Can't find server name for address 172.16.0.30   If NSlookup can't connect to that IP address, something is fubar with the DNS service on 172.16.0.30.  Can you telnet to port 53 (DNS) on that box?  "telnet 172.16.0.30 53"   Diane From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of steve Sent: Tuesday, June 10, 2003 6:33 PM To: [EMAIL PROTECTED] Still having DNS problems!   I was able to run NLTEST and it passed. Went through both SERVERS and verified that it had 172.16.0.30 for DNS setting. “S2.fanmats.com”.   NSLOOKUP fails on both servers with errors. Please refer to NSLOOKUP.txt.   DCDDIAG.EXE FAILS.
