SYMPTOMS
When a user does one of the following:


 * Logs on to Exchange with an account from a Windows NT domain that is not trusted by the Windows NT domain of the Exchange Server computer.

-OR-
 * Uses the "Use Network Security during Logon" option.

The user is prompted to enter credentials for the target domain.

If the user name contains an extended character (ASCII over 127), such as the character ñ (Alt 0241), the user cannot log on. The correct credentials are rejected with the following error message:

The logon credentials supplied were incorrect. Make sure your username

and domain are correct, then type your password again.

WORKAROUND
To work around this problem, do not use the "Use Network Security during Logon" option, and have the users and the Exchange Server computer in the same Windows NT domain.
