I am 'test driving' a new MacBook with Parallels in our office environment, which has Win XP LAN. The problem is that when I launch Win XP Pro on Parallels, Mac OSX drops its connection to the network drives. It does this periodically after launch, which causes major problems if I am working on a Word document on Mac OSX and some other application in Win XP Pro. I suspect it has something to do with Mac OSX and Win XP Pro sharing the ethernet connection to the office server. Network setup is as follows; Mac OSX 10.4.9 - Built-in Ethernet - IPv4 DHCP configure automatically Parallels Guest-host - ditto Parallels NAT - ditto No proxies Log onto nework using command-k and smb://Kaos/Storm Win XP Pro DHCP Log onto network using //Kaos/Storm (maps drive automatically) Parallels Shared networking is on Thanks in advance
