After a reinstallation of WSUS on a ConfigMgr 2007 server the MP was not working anymore.

I looked in the mpcontrol.log and should see that the MP was not working. I could see no "Call to HttpSendRequestSync succeeded for port 80 with status code 200, text: OK" lines. Those lines will be there if the MP is working as it should.
I could see in the mpsetup.log that it was trying to install the MP again and again but it kept failing.

In the MPMSI.logfile I found the following line:
“Product: SMS Management Point -- Error 25006. Setup was unable to create the Internet virtual directory CCM_Incoming”

After googling the problem I found the solution here.
The Bits service had to be reinstalled. After doing that the MP installed successfully

When installing a ConfigMgr 2007 secondary site I have seen several times that it keeps showing "Install Pending" in the ConfigMgr console.

There are several problems that can lead to this. I will try to mention the problems here and how I have solved them.

I had a ConfigMgr 2007 installation where the DB was placed on a SQL cluster.

ConfigMgr was configured to do a backup every night but it failed every time.

A look in the backup log showed the following error:

Info: Sending message to start the SQL Backup…
