Everything working fine in Desktop 3.0 then upgraded to 4.0. My Windows 2003 server (Guest OS) needs a specific IP address to be used as Ethernet (bridged). But when Desktop 4.0 was installed it took the IP address that is needed by the guest OS so now when in Windows 2003 and I set the IP manually I get the following error: "The IP addresess 10.10.101.25 you have entered for this network adapter is already assigned to another adapter `Parallels Network Adapter`. The Parallels Network Adapter is hidden from the Network connections folder because it is not physically in the computer... So - how do I change the IP address of that hidden network adapter? FYI- I`ve done many things, reconfigured the VM, changed how networking works - but every time I go back I get this error message. AND I've loaded a new Version of DT4 Build 4.0.3540 Nov 21) Unfortunately I need that IP address because this is the remote backup system in a point-to-point connection over a dedicated T1 where all the hardware specifies the hard coded IP address. Help my backup server has been down several days now. Is the only solution to go back to DT3?
