I'm not sure what Hace is talking about. I registered as a new user and logged in ok using nt authourization. I can't even find the code he is reffering to, in the register.asp file, from the 3.4.04 version.
The closest I come to his code is line 440 - 442:if strAuthType = "nt" then
strSql = strSql & ", " & "'" & chkString(strDBNTUserName,"SQLString") & "'"
end if
But he has strNTUserFullName in his code.
Maybe he modified his code previously? I'm unable to reproduce this.
