OWA fails and IIS Manager problems after Windows 2003 SP2 install

[IT@C]

Hi,

We have an OWA server on a Front End server.

When I installed Windows Server 2003 SP2:
1. OWA no longer worked
2. IIS Manager did not show any servers in the list

I am logged in as Administrator of the Domain.

comments:
1. In IIS Manager, when I try to Connect to the server (Actions > Connect) I
receive the error:
You have been denied access to this machine

2. In Event Viewer > Application log I see the following errors:

MSExchangeMU
Error 1009
Failed to access the metabase, error code is 80070005 (Access is denied.).

userenv
Error 1090
Windows couldn't log the RSoP (Resultant Set of Policies) session status. An
attempt to connect to WMI failed. No more RSoP logging will be done for this
application of policy.

MSExchangeSA
Error 9097
The MAD Monitoring thread was unable to connect to WMI, error '0x80070005'.


3. In Event Viewer > System log, i see the error:
Service Control Manager
Error: 7023
The World Wide Web Publishing Service service terminated with the following
error: Access is denied.


I uninstalled Windows Server 2003 SP2 and I had access again to IIS and OWA.

Any assistance is welcome in getting Service Pack 2 installed.
