I have attempted to reregister the dll and also to replace it however it did not solve the issue, the instance of Exchange can not find the server and or the database on startup. I have attempted to uninstall all the Exchange rolls and have been able to
remove all but the mailbox and Management Tools, when I do I receive this:

Since I do not have access to EMS and can not perform any of the necessary requirements to remove the mailbox role and uninstall all of exchange and attempt a reinstall.
 Any help with this would be most appreciated.

Answer 1

Thank you for the reply, I have checked the applicationHost.config as indicated, and the path shown is the same as in the error message, there is no D:\Exchange,Server\V14\Bin\ path, it is as indicated in the error D:\Exchange2010\Bin\. Here is the section
from that applicationHost.config file:
<add name="CertificateMappingAuthenticationModule" image="%windir%\System32\inetsrv\authcert.dll" />
            <add name="UrlAuthorizationModule" image="%windir%\System32\inetsrv\urlauthz.dll" />
            <add name="DigestAuthenticationModule" image="%windir%\System32\inetsrv\authmd5.dll" />
            <add name="IISCertificateMappingAuthenticationModule" image="%windir%\System32\inetsrv\authmap.dll" />
            <add name="IpRestrictionModule" image="%windir%\System32\inetsrv\iprestr.dll" />
            <add name="kerbauth" image="D:\Exchange2010\Bin\kerbauth.dll" />
As indicated in my post, I have replaced the kerbauth.dll from another functioning exchange 2010 installation and it has not corrected the issue.
At this point I am looking for a solution for removing the mailbox role and being able to complete the uninstall of exchange and perform a clean install.
Any additional help with this is very much appreciated.
