Also check to see if virus scanning is running on the db files.
I was shocked when I found they were running it on db files when I started here.

On Windows, the best tool to use to discover what is "locking" a file or other process is Sysinternal's procexp.exe. Handle is great, but in this case the GUI is a little better.
The "find" option is particularly helpful in this situation. It will pinpoint exactly what is attached to a file or process and has easy options to kill the process tree.

I've not had to reboot a box because of file locks since I started using this tool years ago.
The locking issue is not with Windows, it is with how Oracle calls and uses the Windows file object class via the Service Container. I've created lots of apps that don't have this problem. I don't know why Oracle can't figure it out. I always laugh when it happens because it seems so unnecessary. J

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:
c: File C:\WINDOWS\SYSTEM32
d8: Section \BaseNamedObjects\*oraspawn_buffer_ts50*
f4: Section \BaseNamedObjects\ShimSharedMemory
...
624: File C:\oracle\product\10.1.0\oradata\ts50\USERS01.DBF
628: File C:\oracle\product\10.1.0\oradata\ts50\EXAMPLE01.DBF
62c: File C:\oracle\product\10.1.0\oradata\ts50\EXAMPLE01.DBF
...
664: File C:\oracle\product\10.1.0\oradata\ts50\SYSTEM01.DBF
668: File C:\oracle\product\10.1.0\oradata\ts50\SYSTEM01.DBF
66c: File C:\oracle\product\10.1.0\oradata\ts50\UNDOTBS01.DBF
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.
