Resolution

This error means that there is a problem connecting to the SQL server. Hosted sites can follow the same troubleshooting steps used for the pre-logon handshake error.

Here are the common causes of this error:

• The ATLAS SQL Alias Manager could be set up incorrectly, so double-check this article.
• Have your institution's network administrators ensure that ports 1433 or 1344 are open for traffic to and from the database. To use port 1344, see this article.
• If you continue to have issues, please contact OCLC Support.
