I have a NT 4.0 workstation that was having comctl32.dll failed error pop ups. When I tried to replace this file I renamed it to "copy of comctl32.dll". Now I get a blue screen after boot up. I have tried using the 2000 recover console and was able to get into DOS to try to rename it back, but the workstation crashed and now recovery console does not work. I get missing hall.dll and it has to abort. I made no changes with the RC. I do not have a current ERD either. I've treied a few dos tools but none have the ability to just go in and rename a file like in DOS. What is the easiest way to get this file renamed? How do I get into DOS to rename a ntfs file?
