text: how can i delete the server i created? im so curious if its posible that you could create a server even in a single computer, so that's why i created a server to my pc, and now im having a problem by erasing that server to my computer. i'm trying to erase it almost one month but nothings happened. my head is aching with this problem i created. please help me how to change it back to original. please help... details os ,hdd partition,  version? if you are talking about domain, you can remove it my dcpromo,  and if you are talk that you had installed a client and server operating system both in the same computer, and you want to remove server.  there exists that if had installed it on other partition on hard disk, then you can simply log on into client os, and format the server os partition, edit boot.ini (hiddin file) and remove the server line from it.  if you had installed both on the same partition, then you can not remove it(although you can, but will create difficulties, only experts are suppose to do). you may ireformat you partition and re-install client os.  good luck
