>>I'm trying to use GetLastError API call to figure out why a call to LogonUser may have failed. However, no matter what I do, GetLastError always returns 0. LogonUser will return 1 when I enter a valid username/password. If I enter the same username with a bogus password, LogonUser returns a 0 indicating there was a problem but GetLastError() still returns a 0.
