If have declare the GetlastErr before declaring the logonUser
also on my situation the return value off logonuser is 0

The getlasterror = 120
120 This function is not supported on this system. ERROR_CALL_NOT_IMPLEMENTED

I did not understand the ASCI and UNICODE stuff from (Paul Vlad Tatavu)
I changed the declaration in AS LogonUsera and AS LogonUserw but no result
Checked on win98 machine accessing an NT domain and server



>Using this code, I get a '0' result. I am running NT Wks4
>and am a Domain Admin on a network (strictly NT Servers).
