Here's what's going on. I've got a server, which I'm calling MYSERVER, running Microsoft SQL Server Express 2005. Right on this server itself, I've got an ODBC connection set up pointing at itself, and that already works perfectly. I log in using SQL Server Authentication (not Windows authentication), and it's set up like this: Like http://serverfault.com/questions/82007/how-do-i-get-this-sql-server-odbc-connection-working I said, that one works. But next, I've got another computer which is on a totally different domain/not on the intranet, that needs to access this same SQL Server hosted on MYSERVER. Because it's on a different domain, it doesn't recognize the name "MYSERVER"; I have to point it at the IP address of MYSERVER, which we'll say is 123.456.789.012. But the ODBC connection doesn't seem to work there. I tried setting it up like this: This doesn't work. When I put in the username and password and press Next, it stalls for a good 10 to 20 seconds, and then finally comes back with the following error: Connection failed: SQLState: '01000' SQL Server Error: 1326 [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Connect()). Connection failed: SQLState: '08001' SQL Server Error: 17 [Microsoft][ODBC SQL Server Driver][DBNETLIB]SQL Server does not exist or access denied. If I try the same thing, but change the "server" from 123.456.789.012\SQLEXPRESS to just plain old 123.456.789.012, I get a different error: Connection failed: SQLState: '01000' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionOpen (Invalid Instance()). Connection failed: SQLState: '08001' SQL Server Error: 14 [Microsoft][ODBC SQL Server Driver][DBNETLIB]Invalid connection. Now I know what you're thinking. You might be thinking, "duh, you probably didn't open the firewall for port 1433, dummy." Except I did, and I verified this, as I can successfully run: telnet 12
the previous tutorial. After clicking Next on the SQL login information screen, ODBC manager will try to connect to http://dba.fyicenter.com/faq/sql_server_2/Getting_Connection_failed_Error_on_DSN_Creation.html the SQL Server with the login information you provided. After a period https://community.spiceworks.com/topic/372789-sqlstate-08s01-08001-connection-failure of waiting time, you may get error message box saying that: Connection failed: SQLState: '01000' SQL Server Error: 53 [Microsoft][ODBC SQL Server Driver][DBNETLIB] ConnectionOpen(Connect()). Connection failed: SQLState: '08001' SQL Server Error: 17 [Microsoft][ODBC SQL Server Driver][DBNETLIB] SQL Server does not exist or access denied. See sql server the picture below: Three possible reasons for the failing: Wrong server name - You provided an incorrect server name. SQL Server not configured to take a network connection - You need to check the SQL Server configuration. Wrong login name or password - You provided incorrect login name or password. The first and third sql server error reasons are easy to validate and correct. The second reason requires further investigation.

Creating your account only takes a few minutes. Join Now So we've been having issues with network connection loss at our company with the SQLSTATE = 08S01, or SQLSTATE =08001 error message. We have multiple servers which have applications running on them that client systems connect to and retrieve data from. One of our servers has a Microsoft mySQL Server database running on it. However both the mySQL server and the other server that clients connect to are having network issues. If they get connected to the server straight through a remote desktop connection, they do not experience any network issues, which is odd because they are still connected through the network to the server. Either way, these problems don't happen at a given time, they are completely random, and unexpected. Sometimes we can go a full day without an issue, while other times we can have the issue multiple times within an hour or day.

Here is what I have tried: Disabled Windows Firewall on all systems Disabled all Power Saving Features on all the system, including the NIC. Checked DHCP configuration, and made sure everything is set up correctly. Made sure there are no IP conflicts or odd IP leases. Can do nslookup on all systems both with IP, or system name. (However, when the issue happens, the servers are not available, and you cannot even ping them) Checked cable connections and replaced all network cables going to the servers and key locations.
