HTTP Error  503. The  Service is unavailable

 

This  error  appears when opening UPM and  Webconsole . Browsing  to localhost  (e.g. http://localhost/wac ) received same error   “HTTP Error 503. The service is unavailable”

 

The 503 Service Unavailable error is an HTTP status code that means the web site's server is simply not available right now.

 

Event log message: ‘The Module DLL C:\Windows\System32\inetsrv\HipIISEngineStub.dll failed to load. The data is the error.’

 

Reinstalling  IIS server or  reinstalling  webservice and webconsole will not resolve this issue .

 

Even If you try  remove Host Intrusion Prevention (Host IPS) 8.0 from a Microsoft Server 2008 running with IIS 7.0, the ISAPI filter references  do get removed from the IIS applicationHost.config file. 

 

The problem is in conjunction with a McAfee update on a web server

To Fix this  you need to perform following steps:

Edit the IIS 7.0 applicationHost.config file and remove the following configuration lines:

Go to  Start > Run -  type ‘ explorer ‘ and click OK.

Navigate to: %windir%\system32\inetsrv\config

Open the file ‘ applicationHost.config’ as Administrator  and  select  Notepad to edit the file.
 

Edit the <globalModules> section and remove the following line:
<add name="MfeEngine" image="%windir%\System32\inetsrv\HipIISEngineStub.dll"

 

Edit the <modules> section and remove the following line:

<add name="MfeEngine" />
 

Once  you are done  editing the applicationHost.config file, save the file, then restart the IIS server

From command prompt type ‘  iisreset ‘

or  restart the system.
