Directory Programming .NET

Im trying to authenticate Intranet site users using Active Directory, everything is working fine with users who have logon access on the hosting server, but for users who dont have that access its not working and giving me an error

Is there something im missing, or i should give all users logon access to the server ? ?

please i need this urgently

 

Thanks

 

How are they being authenticated?

via Active Directory

Click on User Properties >> Access >> Logon (i guess) >> add the workstations that the user has access logon

do u have any idea how can i solve my problem ??

Please really this is urgent

 

Thanks

What I meant was what type of code is being used to authenticate the user?  Are you calling LogonUser or doing something else?  We need to see the code.
