Unexpected error refreshing server manager

We received the following error on the Server when opening roles in Server Manager:

Unexpected error refreshing Server Manager: Exception from HRESULT: 0x800F0818

I have investigated this and found the resolution to be the following:


  1. Download and run the Microsoft update readiness tool at the following location: http://support.microsoft.com/kb/947821

  2. Once it has completed you will find the log it generated in C:\Windows\Logs\CBS\Checksur.log

  3. In our case it generated the following errors:


Unavailable repair files:

servicing\packages\Package_for_KB2393802_RTM~31bf3856ad364e35~amd64~~6.1.1.1 (2).mum

servicing\packages\Package_for_KB2524375_SP1~31bf3856ad364e35~amd64~~6.1.1.1.mum

servicing\packages\Package_for_KB2393802_RTM~31bf3856ad364e35~amd64~~6.1.1.1 (2).cat

servicing\packages\Package_for_KB2524375_SP1~31bf3856ad364e35~amd64~~6.1.1.1.cat

From the above we can deduce that we need to download the update packages of KB2393802 and KB2524375. Once we have the files we can proceed with the next step.

  1. Extract the contents of the .msu files with the following command “Expand  –F:* updatename.msu c:\whereyouwantthefiles” You will then need to open the cab files that are extracted. This can be done by using winrar.

  2. Contained in the each cab file should be a update.cat and a update.mum you will need to rename this to the packages which are generating the errors example: Package_for_KB2393802_RTM~31bf3856ad364e35~amd64~~6.1.1.1 (2).cat

  3. Once completed you should then copy the files to the following directory C:\Windows\Servicing\Packages

  4. Once completed you can run the readiness tool once again and check the log file. In our case we were still receiving the following errors:


Unavailable repair files:

servicing\packages\Package_for_KB2524375_SP1~31bf3856ad364e35~amd64~~6.1.1.1.mum servicing\packages\Package_for_KB2524375_SP1~31bf3856ad364e35~amd64~~6.1.1.1.cat

 

If you do encounter this you may have to check the contents of the cab file and get the files with the exact filenames in question from the cab and copy them into the C:\windows\servicing\packages directory.

 

You will then be able to open Roles in Server Manager once again.
