Trying to delete files and folders from NSS volume on OES2SP1.

when doing this from Windows XP explorer with client32, it is giving me
"Cannot remove folder xxx - cannot find file specified file"
some folders it removed but some seem to be "stuck".

On Netware I would go to NRM and try to delete from there, but that
doesn't seem to be possible in OES2, there is no option to do that in NRM?

How to proceed?
