I want to replace a dll file in system32 with another one. It says I need permission.

Is there a command in cmd that can replace this with another one? Or any other way to do this?

If you use the built in Administrator, you will have the necessary permission.

That being said use extreme caution when accessing a dll account, be sure you know what you are doing. You can cause problems that you may not be able to resolve. Before starting, create a system restore poing.

Most programs will search the folder where the exe file is located for a DLL before the system folder. So if you just need a different DLL for a program or two, try copying the DLL to the same folder as the exe file(s).

Most files in the system32 folder are owned by the TrustedInstaller account and even the Administrator account does not have permission to replace them. This is a part of Windows Resource Protection and is a good thing. If really necessary it is possible for an administrator to replace such a file but I will not describe the procedure. Many system files are normally in use and cannot be replaced while Windows is running. Many system files are part of a set and cannot be replaced individually.Replacing system files is not to be taken lightly and you really need to understand what you are doing. Get this wrong and you could have an unbootable system.

Whatever you are trying to accomplish there is usually a better way, such as what MilesAhead has described.

I suspect for example hal.dll is corrupted. Is there anyway to replace this with the original from the windows disc? I tried repair but it found nothing.

Run an MD5Sum on both dlls. If the installed one is corrupted it should show a different string. You should be able to read it with any account.

Thanks, worked easy.

But I also need to check md5 of ntoskrnl.exe 60.6002V. Is there a way to get that off my vista disc onto desktop?

From a command prompt change to the root of the optical drive that has the disc and do
dir ntoskrnl.exe /s

on XP the system files were under i386 but I don't know where they are on the Vista disc. Maybe someone else knows.
