Please check for firewalls on the client machines and server.
Check for particular ports being blocked by the firewall or a router.
These ports will normally be:
TCP Port 1433 (for SQL Server service)
UDP Port 1434 (for SQL Server Browser service)
You may need to add exceptions for these ports if they have been blocked

Authentication and logon
Mixed Mode authentication is required in order to deploy and maintain Lucid network products. For example, the database installer tool used by Lucid network products when first launched needs the ‘sa’ account and its password in order to complete its job.
There is a way to change Windows authentication into Mixed Mode authentication. See this link below:
