Ok then lets find out. For a first trial I would recommend this: Disable Services config page (much better in next version) In Tweaks don't use ANY of the Network Tweaks, they are probably the cause because you don't even read how dangerous they are. For some they may be ok and even more secure but generally they break things. Why did you add so much Network adapters and none of them isn't applied because you haven't entered the MAC adress. Use it with clean installation files, with sp2. For second trial do all from the first + don't integrate RVM pack, even though it's unlikely to be the cause. There, now I go to sleep, until tomorrow...
