Hello all,
Sorry if this has already been addressed however I was unable to find an
answer on this one.
Does anyone know how to eliminate the problem of a Win2K pro system starting
and when VNC is being started we get an error of WinVNC already registered.
I have gone thru the process of removing all registry entries, except those
of legacy_winvcn as no access to those entries and re-installing and still
gettingthe same error. 
If anyone can help that would be greatly appreciated.
