Summary :
When initiating a SAPGUI link through Netweaver Business Client (NWBC), users may encounter an error stating "partner xyz not reached. WSAEADDRNOTAVAIL." This issue often stems from improper NWBC runtime configuration or network problems. To resolve, verify network connectivity using SAP note 500235 and attempt a direct connection to the server via SAPGUI with specified command lines indicating the server and service number from the error dialog. Further steps include validating service numbers and applying related SAP notes 1155862 or 1098315 depending on the exact scenario. Always attach relevant debugging outputs when escalating issues.
