SCOM 2007 R2 Reporting reports "Client found response content type of ‘text/html’, but expected ‘text/xml’"

When attempting to access the reporting part in the SCOM console we found that we were getting an error message similar to the one below:

This is caused by IIS using a 32bit worked process on a 64bit system.

To resolve this we had to run the following:

1. Open a command prompt and CD to C:InetpubAdminscripts

2. Type in the following and press enter:

cscript adsutil.vbs find Enable32BitAppOnWin64

3. Type in following and press enter:

cscript %SYSTEMDRIVE%inetpubadminscriptsadsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0

4. Type in following and press enter:

%SYSTEMROOT%Microsoft.NETFramework64v2.0.50727aspnet_regiis.exe –i

If you then go back into SCOM and open the Reporting part you should no longer get an error:

Cheers
