Advice needed please.

Over the years Level II oplocking has been causing corruption problems on
NetWare servers and is disabled by default.

Now with NetWare 6.5 SP5 is it working? and with which client32?

Here's the problem, running MS Access 2003 database extremely slow on the
NetWare server, but fast (like 10x faster) if running off of a Windows
Server 2003, tracked it to oplocks... but reading about the history of
oplock problems with NetWare I'm afraid the Access database will get
corrupted on the NetWare server if I turn oplocks level II on, as this is a
business critical apps we can't afford for it to get corrupted. Please
advise. I would hate to have to lose another NetWare client to Microsoft
because of this.

Thank you,
