Win2K server fails to download & install Windows Update via ISA

[Guest Terence]

I am using ISA E.E 2006. I can run Windows Update on both IE6 + XP or IE7 +

XP, I can download and install Windows Update from Microsoft web sites for

these two PCs via ISA server without problem.

 

However, I failed to download and install Windows Update for my Windows 2000

servers via the same ISA server (I used the same credentials to authenticate

ISA just i did for Windows XP) and followinge event was logged in the System

Log of server.

 

Event Type: Error

Event Source: Windows Update Agent

Event Category: Software Sync

Event ID: 16

Description:

Unable to Connect: Windows is unable to connect to the automatic updates

service and therefore cannot download and install updates according to the

Could anyone tell how to fix it.
