First thing I notice after resume'ing an XP SP3 system is that the network drives cannot reconnect, although the shared home directory is OK. Then I realise that the VM has lost it's network connection. Reported this as 7638932, ver 6.0.11992. I can either restart the machine (except that this particular VM refuses to restart - it always shuts down and needs a start from scratch), or by messing about switching between Bridged and Shared networking and between default and en0 devices, I can restore the connection and the network drives reappear with working internet connection.
