I implemented SUS about 3-4 months ago for my LAN. It is wonderful. You can even configure GPO to automatically schedule updates to your workstations. Since the new version has been released, SUS will now do service packs.

I recommend it and it is easy to deploy.

After a long time of complaining on how we needed a real system of patch management (more that just me going to every server and workstation in 2 different locations, patching), it took Blaster outbreaks at 4 different remote office locations to make implementing SUS important!
Now, in my office (in both locations) I did NOT have a Blaster outbreak! But in 4 other company locations, they were slammed with it!
Now for the past month, we have been actively using SUS. We are not running AD, so we have had to resort to .REG files in login scripts to push it out to the clients. But so far, so good.
Clients are talking to the SUS server, getting their updates, and when the users reboot, the updates are applied. The REG file we are using contacts the SUS server every day and installs any necessary patches. But we are not rebooting after that. The users get a popup window when the patch install is done, asking if it is OK to reboot or not.
I have told my users to click NO, and just reboot normally.
So, patches are being rolled out, but not necessarily applied every day, but that is some risk we are comfortable with.
WE apply the patches as they come in for distribution through SUS. WE don't automatically approve of patches until they have been tested on a few test machines first.

Are either of you using SUS across WAN links or are you standing up a virtual server at each site?

If across WAN links, with what type of success? How many clients at the site across the WAN link?

I have one central SUS server in my Main Office that supplies updates to the following offices/systems. I setup a GPO that sends the updates to each office at 1 hour increments starting at 1am. The SUS server synchronizes with Microsoft at midnight.

Main Office - 40 systems - T1
Office 1 - 15 systems - 768K SDSL
Office 2 - 4 systems - 512K SDSL
Office 3 - 2 systems - 512K SDSL
Office 4 - 1 system - Shared T1 with rest of bldg.

All of my offices are connected via VPN. I run MRTG on a Linux box to monitor bandwidth and have no problems with bandwidth because of SUS. The trick was to find the increments to update each office.

If you have a LAN/WAN that has a greater amount of systems being updated, I would recommend additional SUS servers in each remote office.

I tried unsuccessfully to implement SUS when it was first released and shelved it as just another piece of MS software that doesn't work as advertised. Since then, MS has released an updated SUS that does work with our Small Business Server and it has been working almost flawlessly. We had only one workstation that wouldn't update (out of about 50) and I found a tool from MS that cleans up a failed or stalled update. After applying that tool, the final holdout updated and now everyone is happy. Even the SP4 update went smoothly. We manually approve updates before releasing them and allow end users to choose when they wish to reboot. My only wish is that new update notifications be emailed to me when received. As it is, I have to check the update log every day, but it's sure a lot less work than running around to 50 workstations every couple of days! I highly recommend this software.

What utility did you find that "cleans up a failed or stalled update"

It would make sense for ISPs to use SUS as a way of
improving Internet security. However, they would have to
identify users who do not use Windows on their network as
SUS would be pointless for them.

My company decided to set up the SUS update server on a static IP, and my users connect to it over the Internet.
We registered a DNS A record for it and everything.
I even update my home computer over the Internet from the company SUS server.
Currently, we have offices in two cities using our SUS server, with plans of adding the remaining offices (in about a dozen other countries) to it.
So far, so good.

I'd say SUS is comparable to receiving a government issued car in a commie country after waiting on the list for years and years. It does the job in a crude way, but you are grateful that you don?t have to walk or bicycle.
Microsoft has the resources and ability to quickly bring SUS up to a decent product.
The problem is, by doing so Bill Gates won't be hearing the cash register bells ring.

I think of it this way, Microsoft is re-affirming it's commitment to security every few months, so they had to do something for the masses to address patch management.
But it's probably killing them that SUS could affect sales of SMS Server. Therefore they must keep SUS a bit on the Lame side.

SUS needs:
Better logging / analysis

More extensive and flexible Group policy controls. For example you should be able to schedule it by the minute not the hour. It should also have the ability to be scheduled for multiple days of the week, instead of everyday or a specific day.

SUS should be able to manage non-critical patches

A roll back option to roll back some of Microsoft?s Bogus Hotfixes

Old hotfixes and service packs should be able to be deleted without them re-synchronizing and downloading again.

etc etc. etc.
