This IM program was working well on my computer prior to creating the VM and moving with Parallels 5 to a new iMac. We are on a domain. I am able to use the XP Pro Guest OS with no problems. LanToucher works to send and receive messages, but will not populate the list with the people available. I have forwarded all ports (137-139, 445) to the IP of the Guest OS, but still no joy. Any ideas?
