Cannot log into Changepoint / SQL Server connection issue (v2014)
SYMPTOMS
When logging into Changepoint, a server error message is displayed and the login page does not show up
ERROR
A network related or instance specific error occurred while establishing a connection the the SQL server.
To check the connection, the SQL Server was pinged and it was successful.
RESOLUTION
This is not a Changepoint issue but related to the local network infrastructure.
Pinging the SQL Server is not sufficient to test the connection. SQL Server listens on port 1433 by default. To test this (Windows 2012), please issue from a PowerShell:
Test-NetConnection XXXXX -port 1433
for XXXXX put your SQLServer name. Then have the IT department check the output.
