I've got parallels running xp & 98 under OS Xfor some old legacy apps, but for some reason parallels VM's are killing the TCP/IP on my Windoes 2003 Server, it works for a while, then the server loses all network connectivty to all machines ( using TCP/IP protocol, it looks as though other protocols are unaffected ) a server reboot sorts it out for a while any ideas as to why this would happen. What the most reliable setup for networking a VM.
