Hello Recently I had downloaded INTERSOLV ODBC driver from internet and trying to get connected to personnel ORACLE72 on WIN95 and I am getting error. Previously I was able to connect ORACLE using ORACLE ODBC driver and specifying connect string as DNS=PO7;DBQ=T:tcploopback.world. I had tried to enter this information in INTERSOLV driver setup dailog [server name] as DSN=PO7;SRVR=TNS:tcploopback.world, then I got this error *[INTERSOLV][ODBC oracle driver][ORACLE]ORA-12154:TNS could not resolve service name Does anybody know what I should enter in Server name dailog to get connected to personnel ORACLE72 on WIN95 standalone PC. I am blocked with ORACLE ODBC driver as its fail to function properly and not able to get connected with INTERSOLV drivers, please help me. Thank Q In Advance Waheed.
