Have you enabled TCP/IP port in SQL Server Configuration Manager ?

this just solved one of the issues I was facing

Hi Uday,

I created an instance SQL01 for DB. I see this instance as running. The TCP/IP port of this instance is 1433.

When I am trying to install NW 7.0 from install.bat C:\usr\sap\F48\install, I get this error. I tried connecting to the database directly (using Query Analyzer) and I am able to login with the user id and password provided in the log file.

Please let me know how to proceed.

Regards
