Oracle error occurred, but the error message could not be retrieved from oracle

Question

Hai frndz, This is the Error I am getting when I am trying to connect to Oracle (ver 7.0), from VB .NET application (.net ver 2003 and 2002) "Oracle error occurred, but the error message could not be retrieved from oracle" The connection string is: Provider = MSDAORA;User ID=xyz;Passowrd=xyz;Data Source=123; But it is working in few machines but not in few. What should i do? Should I configure Oracle client in any other way. I tried the following methods ==================== 1) I found some solutions in net. There it was given to check the Oracle_Home path in REGEDIT. I checked. The path is correct. 2) Then, one more solution was given, telling try with OLEDB. That also is giving error. 3) I tried by giving large value for "command.connectiontimeout". Not working. 4) The program is connecting in DEBUG mode. But not thru EXE. Please help me in solving this...I am struggling to finish my module with regards and please, karthik
