Is the Teradata system setup for Kerberos (Active Directory) authentication?Anyway, I do not think it is a Domain issue. Can you ping the Teradata nodes?Usually a Teradata system has two or more nodes; each node is identified by SystemNameCOPn where n starts from one. For example a two node system FOO will have two DNS entries FOOCOP1 and FOOCOP2. Try pinging SystemNameCOP1 and SystemNameCOP2. There is a network issue If PING shows an IP address but it cannot reach the node. Are you using .NET Data Provider to connect SQL Server to Teradata Database?Thu, 22 Jan 2009 18:36:00 GMTNetFxhttp://www.teradata.com/teradataforum/Topic14190-22-1.aspxHaving trouble connecting to a teradata server on a large corporate LAN. So large I can't find help internally. Getting the 10065 Host Unreachable message. Specifically, it says "The Teradata Server can't currently be reached over this network."I am new to Teradata and to this forum, so go easy on me. I suspect an internal firewall issue is causing the problem. The server is definitely up and running. It is on domain A and I am on domain B several hundred miles away. The folks in domain A can connect to the server but can't see my SQL server. I can see my SQL server but can't connect to their Teradata server.Other than a firewall issue, I suspect a shared trust may or may not exist between the two domains. Either way, am I in the ballpark or is there something specific the error message is telling me?Thanks for your help!Thu, 22 Jan 2009 18:14:14 GMTabparker
