File.Copy locks source file after completion

Question

We are trying to copy a file from a server, down to a local machine in a .NET 2.0 application (C#), but keep having the source file unnecessarily locked. We suspect it is so

Answer 1

I am not able to replicate this on our file servers.

However, I do know Opportunistic locking is disabled since we're using PeerLock by PeerSoftware.
