How to reset client Software Update to point to Apple Update Servers?

Question

Hi folks
I've been messing around with Leopard Server over the last few months, and as part of that, swupdate server in that as well.
I made the mistake of pointing my laptop at it, which is Snow Leopard 10.6.0 - only to later find that Leopard 10.5 server can't server 10.6 updates as it doesn't catalog correctly.
So, I've backed out my changes to the com.apple.SoftwareUpdate.plist file using defaults.
The system version (/Library/Preferences) file now reads:
grolsch:~ wrkadmin$ defaults read /Library/Preferences/com.apple.SoftwareUpdate
LastAttemptDate = "2009-11-13 22:19:25 +0000";
LastResultCode = 100;
The user version (~/Library/Preferences) reads:
grolsch:~ wrkadmin$ defaults read com.apple.SoftwareUpdate
WebKitDefaultFontSize = 11;
WebKitStandardFont = "Lucida Grande";
So, I've removed all the references to my attempted swupdate server, by ensuring no references of "CatalogURL" exist in either file.
I've also quadrouple checked that there's no managed settings enforced from Workgroup Manager as part of Open Directory on the same Leopard server, and there's definitely nothing enabled.
I've rebooted several times, I've restored the original plist file from before I made the changes to point to my local swupdate server, and I've even deleted the ** com.apple.SoftwareUpdate.plist file. To no avail.
Everytime I launch Software Update on my laptop, it's still pointing to the internal server, and it says the local server isn't responding.
I've done this backout on Leopard (10.5) machines with NO problem, but on Snow Leopard, it appears that the software update server is possibly held somewhere else, but I'm jiggered if I can find it.
Can anyone point out the schoolboy error that I've missed somewhere please??
To clarify: 10.5.8 Leopard Server, 10.6.0 Snow Leopard Client
Thanks!
PS - for anyone that picks up on the repost from the client forum, just doing as I've been told and posting here instead!

Hi
Make sure you're not bound to any directory server first. In 10.6 this would be accessed via the Accounts Preferences Pane > Login Options > Network Account Server > Join > Remove any LDAP Server entry. For 10.5 you use Directory Utility in /Applications/Utilities. For 10.4 use Directory Access in /Applications/Utilities. Next launch Terminal and issue these commands
sudo -s
Provide the local admin password when prompted. If you've not set a password set one in the Account Preferences Pane. You won't see the password being typed in Terminal as there's no echo. Follow this with these commands:
rm -R -v /Library/Managed\ Preferences
rm -R -v /Library/Preferences/com.apple.SoftwareUpdate.plist
reboot now
On successful reboot and login you should be OK?
