Guest clock syncs with host only when computer connected to network

I use vmware workstation 6 on xp sp2 host. When I'm connected to my company's network, everything works fine but when I am not connected the clock of the guest machine runs erraticaly, something running too slow, sometimes foo fast and sometimes simply stopping for some 10 seconds each time.

I've already tried all recommendations I could find in vmware's knowledge base but the problem persists.

Any recommendation is greatly appreciated.

Did you try to disable host time synchronisation in VMware Tools to see if it helps?

Yes, I tried that. Nothing changes, the problem is still the same

Does yor VMware Workstation run on a laptop or other hardware with processor speed switching software installed?

My WMware workstation runs on a laptop (Dell Latitude D630, Intel Core2

Duo). Speedstep is disabled in the BIOS.

Tried this:

In rare cases, it may be possible for VMware hosted products to measure the host CPU

speed incorrectly at driver load time, even if the host machine does not have power-saving

features. You can check the "KHZEstimate" line logged in the virtual machine's

vmware.log file to see the estimated speed of your host, measured in KHz. In these

cases, restarting the host system should eliminate the problem.

There are two lines that mention KHzestimate:

vmx| KHZEstimate 2000000

vmx| VMMon_GetkHzEstimate: Calculated 757786 kHz

I reset the host system and the problem persists.

Sorry, I forget the rest, you may have to adjust a setting to reflect this. Read KB 1227.

I've already done that and it doesn't fix the problem.
