Normally as with a router it would be a laptop plugged in through the 
console port. For Updates it would be unplugged from the console and then 
plugged into protected network behind the Firewall. Then You are not 
bridging network to the Firewall. Laurie, Yes I understand (this for those 
that have no idea what we are taking about). So yes, making sure that we 
can keep it "up to shape" and not risk the Firewall. I hope, only one cable 
plugged in at a time.

Stupid question, is the Win2K Pro in a "DMZ" or the "Internal" network? 
What you have stated is that it is visible to the outside world, thus 
attacked. That would also bring up questions about how much more is visible 
to the outside world (unknown). Which reminds me, I am overdue in checking 
how visible (ports) my Firewall is.

As you brought it up. MS stated that they would rename according to product 
ie.. IIS for you got it IIS server, ISA for ISA server OUT for Outlook etc 
ad infintum.. In cases of Win2K server versions I have seen SERVER appended 
for specific "server" only patches. As I still have Shavlik HFNetck 
( installed on this machine I did a quick comparison between 
Windows Update Catalog (which allows download of the specific patch(s)), 
Technet (which is a big sort out what you want and then download the patch 
one at a time) and Shavlik (HFNetchk which has "every one" of machines on 
your network {XP and 2003 have other specific problems}). SUS downloads 
"Everything Security for all the OS' above NT 4.0"
See example below.

q279328.exe - IE55 Sp1 Windows update
Q279328_IE55_SP1_x86_ENU.exe - Shavlik

Windows2000-KB828028-x86-ENU.EXE - Windows Update Catalog
WindowsXP-KB828028-ia64-ENU.exe - Windows Update Catalog
Windows2000-KB828028-x86-ENU.EXE - Technet
WindowsXP-KB828028-ia64-ENU.exe - Technet
Windows2000-KB828028.exe - Shavilk no i64

Yes there is an X86 for the Intel/AMD Processors in the case of this 
version of Shavilk they do not show i64 processors, Alpha, or heaven forbid 
MIPS.. Until Build (about 2183 Whistler) there was an Alpha version (Now, 
Server (2003) and Desktop {XP}). Yes I did have 9 Alphas running "Whistler" 
in a Miniature Large Enterprise Domain Model (MiniLe only 140 DC's).. Yes 
MS did kill off Alphas. Shavlik, also does some "renaming" to fit their 
software version.
