on windows xp guest, if you install any VNC clock breaks

[larryr]

I have built 8 windows xp sp3 guests running under XP-64 current serivce packs - they work as expected with the guest services until I install any VNC program, RealVNC, UltraVNC, or TightVNC, the guest addition that fixes the Real Time Clock (RTC) stops working and does not work if you uninstall the VNC package ( it works if I go to a saved Virtual Disk and restore the image ).

I like the VNC approach as the Ultra VNC View allows imbeded password so I can click once and connect.

With the Remote Desktop App - I have to type the IP or Virtual machine name and then a userid and then a password.

Both the Microsoft Virtual PC 7 and the free VMware work with VNC.

I like VirtualBox better as it seem to use much less CPU and will use all my cpu cores.

How can I fix the clock issue other than what I am doing - running the clock sync program D4 and syncing via tcp protocol every minute with the XP 64 host.

I am on the 3.0.2 VirtualBox.

Have you installed the guest additions?

Have you installed the guest additions?

Yes they are installed. Clock runs fine until you add any version of VNC and it stops working from that point on. Mouse integration still is fine.
