vb.net - No default driver specified -


i trying connect oracle 9i database using below vb code:

strconnection = "driver={microsoft odbc oracle};server=servername;uid=userid;pwd=password"         connect = new adodb.connection  connect.open(strconnection)

the last line throws me below error:

[microsoft][odbc driver manager] data source name not found , no default driver specified

the vb code working fine , able connect dev database in dev server. same script not working in uat server. tns entries fine. both servers of windows server 2008 - 32 bit.

when checked drivers tab in odbc data source administrator, dev server has below entry:

microsoft odbc oracle - 6.00.6001.18000 - microsoft corporation - msorcl32.dll - date

whereas uat server has below entry: microsoft odbc oracle -

the driver microsoft odbc oracle listed in drivers tab of uat server not have version & dll file details. driver not installed properly? if yes, how re install it? please resolve issue.

thank responses.
