Set static port mappings on Exchange 2003 server; now VPN clients cannot use Outlook XP from offsite

We are running Exchange 2000 on a Windows 2000 server that is the Global
Catalog server. We followed the steps listed in knowledgebase articles
270836 and 298369 and set the ports as follows:

Global Catalog Server Port = 1273
Exchange SA RFR Interface port = 5000
Exchange Directory NSPI Proxy Interface Port = 5001
Exchange Information Store Interface Port = 5002
Exchange Site Replication Service Port = 5003

After rebooting the server, PCs in the office are communicating with the
server on ports 1273 and 5000. However, when a user at home tries to login
using CheckPoint FireWall 1 software, this is what happens:

If they create a new Outlook XP profile, they enter the server name
and their last name. When they click on the "Check Name" button, Outlook
prompts them for their name password and domain and then successfully
matches the last name to the address book and fills the box in with the
display name from their e-mail account.

When they then start Outlook, they are asked for their username,
password, and domain. After entering that, Outlook continues to load shows
the message "Please wait while Outlook builds the Outlook Bar" and then
stops and says that it is unable to open the default folders.

The admin in charge of the VPN has allowed ports 1273, 5000, 5001, 5002,
and 5003 through the VPN. A view of the log on the user's PC shows that
communication is successfully made on ports 1273 and 5000. In addition, the
VPN admin has allowed ports 445, 135, 389, 500, and 80.

As I said, this method was working fine before (the only problem being
that each time the Exchange server was rebooted, new ports would be
assigned). Now after listing the static ports, we can no longer access mail
over the VPN. Help!

If we map a drive to a directory on the Exchange server before we
open Outlook, Outlook will then open just fine. How can we get around this
without having to map a drive?
