ping ComputerName often fails "Bob" <86c6c2e6-2146512712[ at ]news.postalias> 6/11/2007 1:29:04 PM Hi, I find that I often can't ping machines (%Computer%) in a different domain than mine that are on the same VPN. However, I most often can ping their FQDN (%Computer%.%UserDNSname%). There is no trust relationship between the domains and the only thing in common is they're on the same VPN and I use the same credentials (UserName, password) to log on to either domain. I have a stub-zone DNS entry for the other Domain in my domain's DNS server. What else do I need to make this more reliable? --- Bob

What else do I need to make this more reliable? DNS is unable to resolve single-label host names because they do not have a DNS hierarchy. It is the responsibly of the client or client software to see only DNS names to a DNS Server by appending non-FQDNs with a domain suffix where the records are located. If you want to access resources in the remote domain by only their NetBIOS name, you will need to add the remote domain to the DNS Suffix search list, use WINS, or use the hosts file. -- Best regards, Kevin D.

Re: ping ComputerName often fails Ganapathy 6/12/2007 10:24:04 AM Hi, Better add the domain name in your host entry. Then u may solve it seems. I faced similar problem in same domain and i do the same step, then it was ok.

Re: ping ComputerName often fails "Bob" <86c6c2e6-2146512712[ at ]news.postalias> 6/12/2007 6:09:25 PM Hi Kevin, I think the times that pinging the computer name (NetBIOS name) works for me is when the Flexible Single Master Operations Role (FSMO) DC is found. I don't have WINS installed. I don't think I've a DNS Suffix search list created, and I haven't yet looked up what a "hosts file" is, but I suspect I don't have it. Anyway, could the availablity of the FSMO Domain Controller be the reason why I find its NetBIOS name on occassion? Thanks for all the info!

By default the Primary DNS Suffix and Connection Specific DNS suffix are added the DNS suffix search list. (Check your ipconfig /all) The hosts file is a text based file located in the %systemroot%\system32\drivers\etc directory, it has no file extension, it is simply named hosts and can be edited to add hosts that required special name resolution That said, I typically don't use hosts files anymore because it can be an administration nightmare. It is much easier to add records to the DNS zone named in the DNS suffix search list. In your case, since you have more than on DNS namespace to search, i.e. domain1.com and domain2.com you should add both suffixes to the list, having stub zones or any other zones won't be enough. You have to add those domains to the DNS suffix search list. If you have an AD environment, as I suspect, you can do this in a group policy here: Default Domain Policy Computer Configuration -Administrative templates -Network DNS Client- DNS Suffix search List > > Anyway, could the availablity of the FSMO Domain Controller be the > reason why I find its NetBIOS name on occassion?

Re: ping ComputerName often fails "Bob" <86c6c2e6-2146512712[ at ]news.postalias> 6/13/2007 6:14:19 PM Okay, I understand it a little better now. I added the two remote domains to my "DNS suffix search list" via GPO. I rebooted the machine and they are now part of it (as displayed in ipconfig /all). I did not add my domain to the GPO and I can see my "DNS suffix search list" no longer has a reference to it. I can ping my local machines just fine (for now anyway!). I presume I don't need to add my own domain to the "DNS suffix search list" because it is displayed in ipconfig /all as "Primary Dns suffix" (and some machines, not all, also display my domain in the "Connection-specific DNS suffix" also. Some machines have no entry for Connection-specific DNS suffix", but they all have "Primary Dns suffix" and also the GPO controlled "DNS suffix search list". I presume having a blank "Connection-specific DNS suffix" is not a problem? btw I have no other GPO setting in the: Computer Configuration -Administrative templates -Network DNS Client Thanks!

Re: ping ComputerName often fails "Bob" <86c6c2e6-2146512712[ at ]news.postalias> 6/13/2007 7:18:57 PM Oh well, that was short lived. One of my local workstations could no longer find the local domain. I guess that means I should list the Primary DNS Suffix as the first choice in my GPO for DNS suffix search list. I did that and now all works great! (I hope!). Thanks Kevin for all your help!
