Hi Russ,

Not sure what happened to the article. Sometimes they disappear. This is
what it said:

FIX: Server Publish May Fail on Dial-up Links
The information in this article applies to: 
Microsoft Internet Security and Acceleration Server versions 2000, 2000
SP1

SYMPTOMSIf you use ISA Server to server publish on a dial-up adapter
link (such as an analog modem, ISDN, or ADSL), the server publish
operation may fail. This problem may occur although you use a fixed IP
address on the dial-up interface. 

When you run netstat -an from a command prompt on the computer running
ISA Server, you see that ISA Server is not listening on the published
port on behalf of the published service. Because of this, no connections
can be made to the server published service. 

Typically, this problem occurs on a slow link such as an analog modem
connection. However, it may occur when you use any type of dial-up
adapter. 

To get the server publishing rule to work, you must turn off and then
turn on the server publishing rule, or you must stop and then restart
the Firewall Service. 
CAUSE ISA Server receives IP address change notifications from the
operating system (OS) when the dial-up link is brought online.
Sometimes, ISA Server may receive notifications before the IP address on
the dial-up adapter is bound to the interface. This causes ISA Server to
reject the dial-up interface as a valid interface for server publishing.


Additionally, ISA Server will miss the next notification (a few
milliseconds later) from the OS when a valid IP address is bound to the
dial-up adapter. Because ISA Server does not receive this second
notification, it does not server publish on the dial-up interface. ISA
Server can server publish on the dial-up interface again when it
receives a new notification. 
RESOLUTIONIMPORTANT: You must install ISA Server Service Pack 1 (SP1)
before you install the following hotfix. 

For additional information about how to obtain the latest ISA Server
service pack, click the article number below to view the article in the
Microsoft Knowledge Base: 
Q313139 How to Obtain the Latest Internet Security and Acceleration
Server 
A supported fix is now available from Microsoft, but it is only intended
to correct the problem that is described in this article. Apply it only
to computers that are experiencing this specific problem. This fix may
receive additional testing. Therefore, if you are not severely affected
by this problem, Microsoft recommends that you wait for the next that
contains this fix.

To resolve this problem immediately, contact Microsoft Product Support
Services to obtain the fix. For a complete list of Microsoft Product
Support Services phone numbers and information about support costs,
visit the following Microsoft Web site: 
http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS
NOTE: In special cases, charges that are ordinarily incurred for support
calls may be canceled if a Microsoft Support Professional determines
that a specific update will resolve your problem. The typical support
costs will apply to additional support questions and issues that do not
qualify for the specific update in question.

To install the fix, run the self-extracting file. You do not have to
restart the computer running ISA Server. If the computer is part of an
ISA Server array, you do not have to shut down the whole array; you can
still install this fix on a one-by-one basis.

The English version of this fix has the file attributes (or later) that
are listed in the following table. The dates and times for these files
are listed in coordinated universal time (UTC). When you view the file
information, it is converted to local time. To find the difference
between UTC and local time, use the Time Zone tab in the Date and Time
tool in Control Panel.

This fix also applies to the French, German, Spanish, and Japanese
versions of ISA Server. 

STATUSMicrosoft has confirmed that this is a problem in the Microsoft
products that are listed at the beginning of this article.
MORE INFORMATIONNote that although you have installed this hotfix, the
Application Event Log may record informational events similar to the
following: 
Type: Information
Source: Microsoft Firewall
Event ID: 14161
Description:
Server publishing rule [My SMTP Publishing Rule] that maps 
10.10.10.10 TCP to 192.168.10.10 for protocol [SMTP Server]
was applied successfully.
This rule previously failed, but now completed successfully.
This event occurs because the first notification that ISA Server
receives from the OS, before the valid IP address on the dial-up adapter
is bound to the interface, fails. The event does not affect ISA Server.
When ISA Server receives the second notification, a few milliseconds
later, it can server publish successfully.
