I have a computer lab with 28 computers. For some reason 2 of my computers cannot conect to the network. I get an error message 'cannot find server'. I am sorry but when it comes to networking i am still learning. These computers were working fine the day before, now its like the network is just not there. I have no idea what to check or look for. Can anyone please help me? I have no idea as to what info you would need to help me so please let me know.
