PSConfig Checks

Below are some typical things you can check when running the PSConfig command when it fails:

1. Check the text carefully, is the server name and logon correct?
2. Is Windows 2008 being used? You may need to make firewall exceptions such as port 1433-1434 (SQL Database Engine)
3. Check that TCP/IP is enabled in SQL Configuration Manager
4. Do the servers ping each other?
5. Do the service accounts (installation and farmadmin) have the relevant SQL rights? (dbcreator, securityadmin and public?)
