The operating system is Windows 2000 sp4
installed with IIS5.0 and Oracle 8i.
Symptoms: I can connect to the database using Oracle's own tools, and everything operates normally.
Using ASP's ADODB and MSADORA to connect to the oracle database prompts a TNS error or the TNS adapter cannot work.
But the program using VB will work.
It was not until later that I suspected that the IIS user did not have enough permissions. During the check, I found that the user name did not match the machine name. It turned out that the machine had been renamed.
So I changed it to a name that matches the current machine name, and everything passed~~
