after installing the last Windows Updates for Windows XP incl. Internet
Explorer 7, all drive mappings connected to a Netware 6.5 Server are in
the zone Internet. All applications startet from this drive mappings get
a security alert.
On other computers, where I have not installed the last Windows Updates
and the Internet Explorer 7 yet, the same drive mappingss are in the
zone Local intranet and the applications work without any alert.
I have updated the Client 4.91 from SP2 to SP3, but that doesn't resolve
the problem.

NetWare 6.5 SP4
Windows XP SP2
Client 4.91 SP3

Is there a possible configuration option at the client to bring back the
drive mappings to the zone Local intranet?
