You can also added the following to the <servicename>.Config this way it does not affect all the services
We had to do to get the Exchange Services to work after RU5 was to add this to existing .Config files and created New Config files for each service that did not start.
Example: for the MSExchangeTransport.exe we had to create this file “MSExchangeTransport.exe.config” this is a Text file and add :
<configuration>
<runtime>
<generatePublisherEvidence enabled="false"/>
</runtime>
</configuration>
For services with existing file just add :
<generatePublisherEvidence enabled="false" />
In-between the <runtime> and </runtime>
Note: Just an addition… It didn’t work for me until I added a space after the “false” value:
<generatePublisherEvidence enabled="false"_/>
