Hi. My VB.Net web application used to run fine on our old Windows 2003 Intranet server. When the server was upgraded to a new machine with Windows 2012 R2, I now get:
ORA-28547: connection to server failed, probable Oracle Net admin error
The SQLNET.ORA files between the old (2003) and new (2012 R2) servers are the same. That is, they both have the line:
SQLNET.AUTHENTICATION_SERVICES = (BEQ,KERBEROS5)
My VB.Net application connects to Oracle using the connection string:
Data Source=(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = mycompany.com)(PORT = 1521))(CONNECT_DATA = (SID = QA)));User ID=xxxxx;Password=yyyyy;
Is there a way to fix the error without modifying SQLNET.ORA? My concern is, if I modify SQLNET.ORA so my VB.Net app would work, other apps on the server might not.
Thanks a lot.
