This error and solution was reported to us by a customer.
When trying to load Easy Projects you receive the following error:
500.19 0x8007007e
"The requested page cannot be accessed because the
related configuration data for the page is invalid."
The error code
means "The module cannot be found". The DynamicCompressionModule is the
source of the error every time for any handler.
After a lot of
investigation and testing the customer found that WSUS caused Easy Projects to
break:
"I did some further digging and found that WSUS enables 64bit
compression on Windows 2008 x64 bit servers. This compression breaks
any 32 bit applications running in IIS. To fix this you must disable
the WSUS compression. You can disable WSUS compression by running the
following command on the server:
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /-[name='xpress']
If need be you can enable WSUS compression again by running this command:
%windir%\system32\inetsrv\appcmd.exe
set config -section:system.webServer/httpCompression
/+[name='xpress',doStaticCompression='false',dll='%windir%\system32\inetsrv\suscomp.dll']
So the short term solution or us is to disable WSUS compression. Long term we are going to move WSUS to a different server."
