Hi guys, Ive recently decided that im going to attempt the 70-290 exam. I am working through the Microsoft 70-290 press book. Due to a lack of resources I have decided to setup by using Virtual PC a server and a windows xp machine. The server i have promoted to a domain controller which I have done successfully. I now want to add the Windows XP machine to the domain that i have created. However when attempting to add the XP machine I cannot get it to find the domain. Even if i ping the server or vice versa i cannot find either machine. I have been looking at this for 2 days now. Is there a logical reason as to why this is happening and can anyone help me so i can continue to my training? Thanks.
