WSUS computer not reporting status : Error 0x800b0001

WARNING: Digital Signatures on file C:\WINDOWS\SoftwareDistribution\SelfUpdate\Default\wuident.cab are not trusted: Error 0x800b0001

This is the error I had in my c:\windows\WindowsUpdate.log while I was trying to get my XP computer updated by the WSUS Server I just installed.

After many time spent trying to fix the error in many way I discovered the problem was simply my WSUS server an old version while the XP machine was serching for a most recent WSUS.

So the solution was simply:

1. install WSUS 3.0 SP2 Over the previous WSUS 3.0 installation
2. install the WSUS patch: KB2720211
2. reboot the server

once the server was up and running:

3. on the client run this script (found in internet) :

net stop wuauserv /y
net stop bits /y
net stop cryptsvc /y

RMDIR /S /Q %systemroot%\SoftwareDistribution_Old
ren %systemroot%\SoftwareDistribution SoftwareDistribution_Old

regsvr32.exe c:\windows\system32\wuapi.dll /s
regsvr32.exe c:\windows\system32\wups.dll /s
regsvr32.exe c:\windows\system32\wuaueng.dll /s
regsvr32.exe c:\windows\system32\wucltui.dll /s
regsvr32.exe c:\windows\system32\msxml3.dll /s
regsvr32.exe c:\windows\system32\wuaueng1.dll /s
regsvr32.exe c:\windows\system32\wups2.dll /s
regsvr32.exe c:\windows\system32\wuweb.dll /s
regsvr32.exe c:\windows\system32\atl.dll /s

net start wuauserv /y
net start bits /y
net start cryptsvc /y

wuauclt.exe /resetauthorization
wuauclt.exe /detectnow
wuauclt.exe /reportnow


And after few minutes I seen my client asking me to install new updates, and on the WSUS server the pc appeared with its status. Problem solved :)

Convert scheduled jobs from XP / W2003 to W7 / W2008 Server

If you need to convert some scheduled jobs from XP to W7 or from Windows Server 2003 to Windows Server 2008 there is this interesting way I found on this blog:
http://simonhampel.com/how-to-convert-scheduled-tasks-from-windows-xp-to-windows-7/

This is how to do it:
On the W2008 / W7 machine open a console prompt with administrative rights and write this:

schtasks /Query /S remote_computer_name /XML > output_file.xml

if you don't have rights on the remote machine you need to specify user/password:

schtasks /Query /S remote_computer_name /U remote_username /P remote_password /XML > output_file.xml

What you obtain is a file, output_file.xml containing all the scheduled tasks from the remote machine.

You cannot import directly this file into the W2008/W7 machine, because it contains all the taks, the import process is expecting a single task instead.

With a copy and paste process you need to create one file for every task you want to import.
This is quite simple, you need to copy and paste from <task> to </task> to a new xml file:

<Task version="1.1" ...>
...
...
</Task>

Then you need to go to the W2008 / W7 machine, scheduled tasks, right click, "Import...", select the file/s you just created and the task is imported.
