SQL server doesn't exist or access denied || SAP NW 7.4 installation || Distributed environment

$

Hello Experts,

 

We're installing SAP NW 7.4 Gateway in a distributed environment (Windows server 2012) where APP server resides on SAPDEVNGAPP1 and DB server resides on SAPDEVNGDBS1. We are using the APP server for both ASCS and PAS instances.

 

I'm able to install the SQL db 2012 on DB host and also ASCS instance is installed successfully on APP server. I'm unable to install the PAS instance because it is not able to connect to the SQL database. Below is the error that I am facing:

Small background on the environment:

-> App server {APP zone} is in different zone than DB server {DB zone}.

-> Both servers are not assigned to same domain (they are put up on WORKGROUP). Can this be the cause that both are not under same domain?

-> Ping <dest IP/hostname> from APP to DB and vice-versa are successful.

-> Telnet <dest IP> <port> are not successful in both servers.

-> I'm performing the installation using Administrator user ID.

-> SQL Database has been installed using setup.exe. We didn't use SWPM (I guess this will not cause a problem).

 

Here is the warning/error captured in thesapinst.logfile:
