Hello,
MSLogon II autenthication does not work on Win 2000 Professional.
In mslogon.log file this error message appears: "Invalid attempt (not authorized) for client ..." .
I work with UltraVNC server 1.0.5 and cross-domain authentication.
VncViewer is 1.0.5. too. Below ultravnc.ini.
I hope that these information are complete.
Thank you.
