If the real problem is that you are getting a different DC when you do PING, that is fine. Although I'm guessing that you are doing a /flushdns between each PING ? If not and you are doing this from the same machine I'm surprised. What you are seeing is Round Robin in DNS. Do an NSLOOKUP on the domain and you should see the same results. A different DC will be listed first each time. DNS doing what it's supposed to do. Getting a local DC for logon authentication is different. If that really isn't working correctly, then you need to take a look at your sites and subnets to see what is going on. It also helps to have an understanding of how a client determines it's local site. This might help:

Sorry, slight change of focus for this question. If I run “set l” from a cmd prompt, it shows me my local DC, which is totally cool. However, if I then ping the FQDN of our domain, the response comes from random DCs from around the network, including non-local ones. So the real question is whether or not that is normal behavior.

Joe Heaton ITB – Enterprise Server Support From: Joseph Heaton [mailto:[email protected]] Sent: Monday, August 20, 2012 12:13 PM To: Heaton, Joseph@DFG; NT System Admin Issues Subject: Strange login issue We’re setting up a new domain. When a user here in the central HQ area logs in, the DC that they use for login is random. Should be a DC here locally, but most of the time it is not. They’ll end up using a DC from a field office site, which means the request goes over slow links to get there. I’m not the architect, but I know that the person that set up the domain used Sites and site links for replication, etc. Using this had no effect, and neither did removing them. Anyone have advice on how to make clients use the local DC if it’s available, before going to another site for login? ~ 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 ----------------------------------------- This message, and any attachments to it, may contain information that is privileged, confidential, and exempt from disclosure under applicable law.
