Hi All,

I've been a bit behind in my windows XP updates recently, and I have about 18 or so I need to roll out to all our users, according to WSUS. I'm trying it on a couple of test PCs, and so far i've had no luck. On each one, one update would install (and need a reboot), and nothing else since. When I run wuauclt.exe /detectnow, I get this in the windowsupdate.log:

I've tried deleting everything in the C:\Windows\SoftwareDistribution, stopping the services, rebooting etc. Can anyone decipher the log to see where it's going wrong? Many thanks!
