A friend gave my son a computer which has Windows 2000 on it. Unfortunately it must have belonged to a Network or something as it won't even let me go into Add/Remove programmes as it is saying that I am not the Administrator. It will not even let me instal any discs for the same reason as it says I don't have permissions. Is there any way round this? Everything else on the computer has been cleared. No documents or anything. I wondered if I reinstalled Windows 2000, would this solve the problem. The computer is only going to be used for basic things and it is a shame if I am not going to be able to use it. Hope someone can help.
