What is the friggin' deal here? Why hasn't this issue with the network unable to connect been resolved?! I spend at least a third of my time trying to make the network connection work and all I can do it reboot, reboot, reboot until finally for some completely unknown reason Parallels' network adapter recognizes there is a connection and grabs an IP. Disabling, re-enabling, changing from shared to bridge, to host-only - it makes no difference. This has been an on going frustration with no resolution or response in sight!
Do you have it reported somewhere? Please follow these standard for networking steps: Click Start -> Run and execute cmd.exe. Type in the appeared window command "ipconfig /all" (without quotes). Stretch the window to make all the output fit and without closing the window, click menu of Parallels Destkop "Help"->"Report a Problem", send a problem report (it is not necessary to provide description) and post here the report ID.
