Hi There is an option if we have vmware tools installed, but that does not work because I have already enabled the synchronization option. And still time get out of synch The ntp server must be my host OS since I am not connected to internet.... Guess I will do that, set up ntp in host OS and run ntpupdate every minute :-S LSC On 3/8/06, Pakhutkin, Maxim (Max) <maxim.pakhutkin@xxxxxxxxxx> wrote: > > I believe there is an option in VMWare Workstation 5 to keep the clock of > the virtual machine synced with the host.
