Hello everyone,
Using Sage300 app online from Seneca College and SQL Management 2014 installed on my laptop! Last week connected perfectly and did an assignment! This week I can connect to Sage online App, but when I start SQL Management it says Error26 can not connect to database! We input the path of database manually as: Mylaptopname/sqlserverexpress. I didn’t do any changes since last week so please help me to solve my problem! Thank you in advance for your time.

    Mylaptopname**/sqlserverexpress**

    It has to be a backslash = \, not a slash = /
    And in common the default instance name is SQLEXPRESS, not sqlserverexpress. So try it with
    Mylaptopname\SQLEXPRESS

    That error means that SSMS was not able to find the SQL Server instance BabakAsus\SQLExpress. There can be any number of reasons for this. The server and/or instance name is misspelled, SQL Server is not running, there is a firewall blocking the connection. Just to name a few of the possibilities.

    Here is a link to a troubleshooter for this error: https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/troubleshoot-connecting-to-the-sql-server-database-engine
