Known issue

After you install this update, you may receive the following error message on a computer that is running Communications Server 2007 "IM Conferencing" or "Telephony Conferencing" server roles:
For the IM Conferencing service (Rtcimmcu):

If you receive this error message after you install the update, create the Immcusvc.exe.config file. To do this, follow these steps:

1. Start Notepad.
2. Paste (or type) the following text into Notepad:

   <configuration> 
   <runtime> 
   <generatePublisherEvidence enabled="false"/> 
   </runtime> 
   </configuration> 

3. On the File menu, click
   Save, and then name the file
   Immcusvc.exe.config.
4. Save the file in the same location as the Immcusvc.exe file. By default, this is in the following location:
   %Program Files%\Microsoft Office Communications Server 2007\Server\IM Conferencing

Start the Services.msc process, and then start the Office Communications Server IM Conferencing service. By using the Immcusvc.exe.config configuration file, the Authenticode signature verification process is bypassed for the Immcusvc.exe file and for all dependent binaries. Additionally, the IM Conferencing service now starts in a timely manner.

For the Telephony Conferencing service (Rtcacpmcu):

If you receive this error message after you install the update, create the Acpmcusvc.exe.config file. To do this, follow these steps:

1. Start Notepad.
2. Paste (or type) the following text into Notepad:

   <configuration> 
   <runtime> 
   <generatePublisherEvidence enabled="false"/> 
   </runtime> 
   </configuration> 

3. On the File menu, click
   Save, and then name the file
   Acpmcusvc.exe.config.
4. Save the file in the same location as the Immcusvc.exe. By default, this is the following location:
   %Program Files%\Microsoft Office Communications Server 2007\Server\ Telephony Conferencing

Start the Services.msc process, and then start the Office Communications Server Telephony Conferencing service. By using the Acpmcusvc.exe.config configuration file, the Authenticode signature verification process is bypassed for the Acpmcusvc.exe file and for all dependent binaries. Additionally, the Telephony Conferencing service now starts in a timely manner.

Note This workaround works only with the Microsoft .NET Framework 2.0 Service Pack 1 (SP1) and later versions. Additionally, use this workaround only if you receive error 1053 after you apply the update on the server.


For the Web Conferencing service (Rtcdatamcu):

If you receive this error message after you install the update, create the Datamcusvc.exe.config file. To do this, follow these steps:

1. Start Notepad.
   
2. Paste (or type) the following text into Notepad:
   
   <configuration> <runtime> <generatePublisherEvidence enabled="false"/> </runtime> </configuration>
   
   
3. On the File menu, click Save, and then name the file Datamcusvc.exe.config.
   
4. Save the file in the same location as the Datamcusvc.exe file. By default, this is in the following location:
   
   %Program Files%\Microsoft Office Communications Server 2007\Server\Web Conferencing
5. Start Services.msc, and then start the Office Communications Server Web Conferencing service.

By using the Datamcusvc.exe.config configuration file, the Authenticode signature verification process is bypassed for the Datamcusvc.exe file and for all dependent binaries. Additionally, the Web Conferencing service now starts in a timely manner.
