0 - 3 of 3 tags for 32-bit connection

I downloaded td-ttu-15.00_for_Windows on my personal computer and created a DSN using my public ip over internet as IP server for DSN.
While connecting the DSN on TDA i am getting "10061 WSA E ConnRefused: The Teradata server is not accepting connections".

I have installed both 32-bit and 64-bit ODBC drivers for Teradata. I have set up the DSN for both 32-bit and 64-bit using the below odbc administrators
for 64-bit - C:\Windows\System32\odbcad32.exe ; DSN Name : DW64
for 32-bit - C:\Windows\SysWoW64\odbcad32.exe ; DSN Name : DW32

I have a 64-bit operating system on a server running Windows Server 2008 R2. I am attempting to create a 32-bit ODBC connection for BusinessObjects XI 3.2. I located the SysWOW64/odbcad32 application to create the 32-bit connection.
