I will add.... I've seen times that Windows will lock files and it dosen't matter what you do (including killing the service) the only way to get that lock released is to reboot the box. THAT is a pain.

  Hi Bill,

  Taking a tablespace offline on windows does not seem to remove the lock that Oracle has on it.
  When a file is open, the process has a lock (don't know the windows technical term for the
  type of lock)

  Just tested this on my laptop: took 10g tablespace EXAMPLE offline, and the handle utility
  (from Sys Internals toolkit) shows that the EXAMPLE files are still open by Oracle:

  I've never restored a tablespace on Windows, but it appears that your   procedure may need to be modified a bit.

  Have you tried restoring the tablespace with Oracle in mount mode?

  Our resident RMAN expert (Robert Freeman) may know the answer to this.
