Errors after removing Exchange 2010

July 14, 2011 by Wayne Small 40 Comments

Working on site over the past few weeks for a larger client and I needed to remove Exchange 2010 from a server that we needed to continue to use – that is to say – I had to make it a clean removal Smile

After following the bouncing ball and removing Exchange 2010 from the server, we had an enormous amount of errors in the event logs every few seconds.

In the System log we had

Log Name: System

Source: Microsoft-Windows-WAS

Date: 13/07/2011 10:19:52 AM

Event ID: 5139

Task Category: None

Level: Warning

Keywords: Classic

User: N/A

Computer: server.domain.local

Description:

A listener channel for protocol ‘http’ in worker process ‘6504’ serving application pool ‘WsusPool’ reported a listener channel failure. The data field contains the error number.

Log Name: Application

Source: Microsoft-Windows-IIS-W3SVC-WP

And in the Application event log we had

 

Date: 13/07/2011 10:31:10 AM

Event ID: 2280

Task Category: None

Level: Error

Keywords: Classic

User: N/A

Computer: server.domain.local

Description:

The Module DLL C:\Program Files\Microsoft\Exchange Server\V14\Bin\kerbauth.dll failed to load. The data is the error.

 

After a bit of investigation, I found that for some reason the kerbauth.dll was still in the IIS configuration file.  To fix this, follow the procedure below.

1. Locate the applicationhost.config file in the C:\Windows\System32\inetsrv\config folder and open it with Notepad.

2. Find the “Kerbauth” reference in the globalModules section as highlighted below and remove the entire line.

 clip_image004

3. Save the file and close notepad.

4. Open and administrative command prompt and run an iisreset.

Give it a moment and your event logs should be clear of these errors.

    If you have a x64 system, the relevant applicationHost.config file may also reside in C:\Windows\SysWOW64\inetsrv\Config\.

    Wow, 4-1/2 years later and this post is still saving butts! We encountered the issue after removing Exchange 2010 from and SBS 2011 box as part of an Office 365 migration. The issue effectively broke the Default Web Site and anything tied to it like SharePoint and the Remote Desktop Gateway.

    Thanks for posting.
