Macintosh clients running Outlook 2001 in Classic - Exchange 5.5

Hi, I'm not sure if this is the correct group to post this question on, but
any pointers would be appreciated.

We have a mixed mode NT 4 and Windows 2000/2003 network in which Exchange
5.5 is installed in two sites. One site is running 5.5 on Win2K server, the
other on NT 4 server. DNS is provided through internal servers on 2003 and
using forwarders for external names. The Exchange servers have external
names, and the internal DNS act as secondaries for the DNS domain they
resolve to.

We have no problems running Outlook 2000 on Win2k or XP clients (only ones
in use), but on the Mac clients, setup of Outlook 2001 has been problematic
lately, and clients that are successfully setup get frequent "drops" from
Exchange.

The Macs are running OS X 10.3.5 or .6 and run Outlook in Classic. A host
file was made and held over from OS 9, which was needed to resolve the
Exchange server names on the Macs (I guess since they don't understand
WINS?). Outlook seemed to be fine on the Macs before we made a change to the
internal network addressing - we reorganized from having all Internet
accessible "real" addresses on the internal net, to using an internal
addressing scheme with a class A network divided into several class B
networks (don't ask).

Anyone have similar problems with Mac clients disconnecting? So much has
changed on our net recently that it's hard to pinpoint where the problem
originates, but the Macs do seem to be resolving the Exchange server names
correctly.

Thanks
