Cannot replace a DLL file in system32

I need to change a DLL file but Vista tells me I do not have permission to do
so.
I am logged in as my User Name with Administrator rights.
I have disabled Windows Defender.
Still can't carry out the replacement.

Can someone please tell me what/how else I need to do?

Thank you heaps.

All the system files are owned by another process to protect themself even from admins, take ownership of the file and you will be able to change the permsions to give you access.

Out of curiosity, why do you think you need to do this?

One good reason to patch a system file is tcpip.sys to increase the tcp connection limit.

Well, I would say that different people would have different opinions on
the "goodness" of that. Patching system files tends to be a bad thing
to do as it could have implications on later updates.
