I've switched to a PCI based network card which seems to have helped. Have to wait and see but so far seems much better than the on-board stuff even though its from the same manufacturer (Realtek).

At the moment I have enabled timeSync with vmware tools.

In the general area of time keeping on the host, I added the following
settings which avoided errors about the RTC missing interrupts:
host.usefastclock=false
host.cpukHz=2400000
host.useTSC=true
ptsc.useTSC=true

I have two other machines similarly configured (with the exception of
running other linux applications not samba).

Ntpdate seems to be installed as it is part of the ubuntu-server default
config. However, my other machines seem to run it ok. If anything they
fall behind a bit and the vmware sync keeps them up-to-date.

How are your time sync options set for the VM? Is it keeping time ok?

True.  I refer to this document from vmware.
http://www.vmware.com/pdf/vmware_timekeeping.pdf

Generally, ntp & vmware timesync fight each other.  The usual method is
to turn off the ntp service, figure out how to minimize interrupts,
allow the clock to run a little slow and allow vmware timesync to bump
up the time when it gets about 1 minute slow.

There's another thread that mentions issues with on-board nics and
drivers.  Over the years, I've bumped into that myself.  To the extent I
 try and use host-only and route whenever possible.  That's worked
better for me in generic usage.
