I have this pc from work, this comp was set it up in a server or network. Now i have this comp at home and i am not able to run or install any software, I tryed to install a new windows but i couldn't, it says check comp for virus or scan disk and do nothing I need to reboot system and press F2 to run windows normally bur still it is running in network mode... Any ideas what can I do? thanks

I think what you're asking is how to un-join a Windows 7 PC from a domain when said PC is no longer attached to said domain and the Domain Administrator is not available?
