I am trying to expand(extract) the ntoskrnl.ex_ in c:\winnt\system32 via Recovery Console on w2k. It says the file cannot be expanded. I did change the attrib -R c:\winnt\system32\ntoskrnl.ex_. When try to view the attri b, it says ntoskrnl.ex_ has a and c attrib, what does a and c means ? Can anyone tells me the whole procedure?
