I had a windows 2000 And it was working very good until I install Windows Xp Pro. Before I installed that I ran the UPGRADE ADVISORY in it say I had no Incompatibilities on my 2000. So I install windows Xp Pro Then in the installing process I had 2 error's I thoght they werent that big but they are. I cant acess the internet and cant run the Trouble shooting guide . Is there when I tried to install the drivers it said ERRO ikernel.exe cannot launch. Everthing else works but the internet part now I want to DOWNGRADE to 2000 again.If you know any solution I can try please help me.
