With Vijeo Historian 4.50 we were facing the problem that data logging stopped frequently. In the event viewer logs there were error related with "Named Piper Server not initialized". How can we resolve this problem.
As per the event viewer logs there were error related with Named Piper Server not initialized, in this case we have Enable Named Pipes and TCP/IP for Microsoft SQL Server as per the below steps :
To enable named pipes and TCP/IP for Microsoft SQL Server 2012:
Click Start > Programs > Microsoft SQL Server 2012 > Configuration Tools > SQL Server Configuration Manager.
Under SQL Server Network Configuration > Protocols for MSSQLSERVER:
Double-click the protocol name TCP/IP and set the property ENABLED to Yes.
Double-click the protocol name Named Pipes and set the property ENABLED to Yes.
After this we have to restarted the Historian Data Service and it should start logging data.
