SAP .Net 4. Connector ERROR: program DEV_TCP not registered.

Hi All,

Created an RFC Dest of type T with the program name and provided the same details along with gateway host and gateway service to the target.Net system.

Running into error <program "DEV_TCP" not registered> RETURN CODE: 679 while performing the RFC connection test.

For the same reason no entry is found in SMGW against the program id.

Want to understand where exactly should the program registration be done,should it be on the .Net system or on SAP ECC? and is there a way to validate the .Net connector installation on the target system ?
