Hi All, Guru's,

I have developed a HTTP/HTML (Web) script. I am using web_set_user function to login to the website using the loadrunner script and the replay works well.

When i run the LR script from Performance Center 11 with 10 Vusers(10 valid real user accounts), I see quite a few errors 26630 (401 authentication errors) but it has lot of passed transactions too. Also, I have validated the user accounts and tested 1 Vuser with PC with no errors.

Now i have checked the option of WinInet replay instead of sockets (Windows only) option and now i dont see any errors.

Is there a problem using WinInet replay instead of sockets option or is the problem something else. I understand WinInet replay is older method of authentication.

Any advise will be helpful.
