Problem connecting to SQL session with users outside the domain

Last Modified: 2013-11-05
I Have a SQL server running on a 2 nodes Cluster with windows 2000 Advance Server, since a few days ago I have the problem that any user outside my domain can connect to this server, i'm using a home made aplication for the users tasks, but it is not the problem because even trying to connect with the SQL Administrator it is not possible. also i have the problem tha in the domain i can connect using the name of the server but not if i use the Server's IP. even if i am in the server it self.

Check your authentication.  If it is set to domain (or windows authentication) I suspect this is whats causing the issue...  I would set authentication to mixed mode authentication.


Hi, thanks for your replay, it's not an issue over the SQL server Authentication, i'm using sql and windows authentication, i think it's an issue over the DNS, but i have no clue what to check

try connecting to the SQL server with query analyser using it's IP address.  If if works, the the issue is DNS related.


I already tried that since the very begining, and no, I can not connect using Query analyser with IP (localy in the node or in any worksatation). In fact this system has 3 IP's and 3 names (physical, Cluster, SQL) ot that six "ways" to connect the only one that it's working it's by SQL name. Now I have done a lot of more troubleshuting, if I'm in the domain, i can connect by name of the SQL instance, if i'm not I can not connect any way, but checking with WireShark, on domain when i can not connect SMB responds NOT_OBJECT_FOUND ,  if i connect to one of ther server's shearings I can connect using name and IP  if I'm on domain, if iIm not even if I connect to the shearing ì cannot connect neither domain or IP and i get a respond from SMB of STATUS_LOGON_FAILURE, Because o this messages from SMB I Think I have a problem between my Cluster and my Domain Controller, but I can not find where or why. I already checked configuration on my AD, and not found problems.


i couldn't find the exact resolution to this problem, i had to reinstall the whole SQL server (i was lucky i had not to install the whole cluster) and it worked just fine again
