Question : SCCM 2007 MP install failing on windows server 2008 r2

Hi,
I am unable to get a management Point installed on a basic install of SCCM 2007 sp2.
2 server install SCCM application Server and SQL Database server.
SCCM Server is windows server 2008 R2 (64bit)
SQL database is running on another server also Windows server 2008 R2 running SQL 2008.
All other components are installing fine.
The error seems to be a common one (from the MPMSI.log)

Product: SMS Management Point -- Error 25006. Setup was unable to create the Internet virtual directory CCM_Incoming
The error code is 80070005

I have removed and reinstalled BITS with no joy.
I have uninstalled SCCM, WSUS, BITS and IIS. Started from scratch and still the error remains.
The webdav setting are configured correctly.
There was a GPO that restricted access to the registry key
HKLM\Software\Microsoft\Windows NT\CurrentVersion\SVCHOST
This is no longer being applied and the permissions have been reset.

As this is IIS 7.5 there is no IIS IWAM account.
Any help or advice would be very welcome.
Below is some more log extracts:

Answer : SCCM 2007 MP install failing on windows server 2008 r2

Just an update.

The problem was due to permissions not being correct on the tasks directory.
Once I reset teh permission the MP installation worked fine.

Thanks for your help.
