The connection to the named instance has failed. Error:

Hi folks,

I am facing an error while installing SOLMAN on an named instance of MSSQL.

Hereu2019s the situation: the server is already running ERP DEV on the default instance, and customer decided to use the same box for SOLMAN, so I decided to install it on a named instance (\SMD), instead of going for MCOD.

During phase 18 of 44 (Import Java Dump), I am getting the following error. Have you guys ever faced this error before?

Thanks for your help,


java version "1.4.2_14"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_14-b05)

      Reason- Due to changes in network IP Address or IP address range of your machine & SQL Server Machine).


      1) Ping SQLServer Machine--TimeOut

      2) Firewall setting


      Correct the IP address range given for SQL Server machine with your machibe newly allocated IP address.

      Change VLAN Setting by Network Admin
