Fax console locks up XP machine on SBS network

We're having a problem with our network where the Fax Console is
"freezing" our Win XP boxes when faxing from an XP SP2 client out
through a Small Business 2003 SP1 server. The freezing initially was
happening on one workstation, with others able to use the Fax console,
but now other workstations are having the same issues. Sending a fax
with the fax printer driver does not cause the freezing--only opening
the fax console causes it.

It looks to me like what's happening is the Fax system is taking over
the network connection and preventing any other network traffic from
getting through. When a user opens the fax console a few seconds later
Outlook spits up a message that the connection has been lost to the
Exchange server. When it's locked I can't get in to the machine via
RDP. The local user can still open the start menu, etc, but any
programs that use network communications are non-responsive. This lasts
for at least 10 minutes and typically requires us to restart the
machine, although we did leave once and when we came back several hours
later the machine was responding.

The workstation is Windows XP SP2, the server is Windows Small Business
Server 2003 with SP1, fully updated including the patches to install
SP2 to XP clients. On the XP client, after these problems started, I
went to Add/Remove Programs > Windows Components and uninstalled XP's
Fax software, then re-pushed the Fax client out from the server using
SBS 2003's Install Client Software feature.

The following are logged in the application log on the client when the
computer is booted, but I'm not sure if these are only displayed
because there is no modem in the local workstation.:

Verify that the targeted device or devices (if routed to a group of
devices) is connected and installed correctly, and turned on. If routed
to a group, verify that the group is configured correctly.

==================================

Note that we are having some other fax issues (some incoming faxes are
failing to be received, and fax notifications are failing to be sent to
exchange mailboxes) but so far I'm treating this as a seperate issue.
This is a previously unused fax installation and I hadn't yet got the
other server features working correctly.

Anyone have suggestions on fixing the freezing on the clients?
