When trying to connect to the OPCDA server using remote connection, receiving the below mentioned two errors. Have given Launch Access to both the Anonymous Logon as well as Everyone on both the Server and Client machine. 

Able to ping to the other machine but the Matrikon OPC Explorer on the Client machine is not able to connect to the OPC DA server and is giving the below error.

Are you able to ping the server? 

May I inquire the vendor of the server you are trying to connect to?
