Hi,<BR>I am developing an logon asp page.In that page User has to enter<BR>UserName and Password.When the page is submitted I am calling a method in an COM object to logon.The method using LogOnUser API(logon with new username and password).The Method is working fine in VB,VBScript.But when the method executes in IIS,It is failing.Error Message is "Logon Failed".Do I needd to configure IIS security settings?I configured the security as Basic Authentication and WindowsNT Challenge/Response.<BR>Thanks,<BR>Palani.
