| Description | The Microsoft Exchange Unified Messaging Worker Process (UMWorkerProcess.exe) was unable to start. More information: %1. |
| Event Information | According to Microsoft : Cause : This Error event indicates that the Microsoft® Exchange Unified Messaging Worker Process (UMWorkerProcess.exe) was unable to start on the computer that is running the Unified Messaging server role. This event may be caused by one or more of the following: 1.A SocketException occurred when the UM Worker Process allocated a socket from the operating system. The socket is used by the UM server to perform network communications with the IP/VoIP gateway. 2.The Globcfg.xml or UMconfig.xml configuration data file does not exist. The default location is C:\Program Files\Microsoft\Exchange Server\bin. 3.The directories that store the UMconfig.xml configuration data file, speech grammar files, or the prompt files do not exist. 4.There are initialization failures on the fax subsystem. The fax service loads the fax service provider to create and initialize the virtual fax devices. The devices are used by the UM server to receive faxes. 5.The finite state computer files, for example, Logon.fsm, Fax.fsm, and DtmfMainMenu.fsm, do not exist. Alternatively, an exception occurred when the files were being loaded. The UMConfig.xml file contains references to the name of all the finite state computer files. 6.The semaphore object that the UM Worker Process tries to access does not exist or the access is denied. Semaphore object is an operating system object that is used to control access to a pool of shared resources. Resolution : To resolve this error, do one or more of the following: 1.Replace the missing Globcfg.xml or UMconfig.xml with the default files that are located in the \Setup\Server Roles\Common folder of the Exchange 2007 CD. The default location to replace these files on your UM server is C:\Program Files\Microsoft\Exchange Server\bin. 2.Make sure that the directory exists that stores the UMconfig.xml configuration data file, speech grammar files, or the prompt files. The default location for the UMconfig.xml is C:\Program Files\Microsoft\Exchange Server\bin. The default location for the speech grammar files is C:\Program Files\Microsoft\ExchangeServer\UnifiedMessaging\grammars\ 3.Replace the missing finite state machine files (*.fsm) with the default files that are located in the \Setup\Server Roles\Common folder of the Exchange 2007 CD. The default location to replace these files on your UM Server is C:\Program Files\Microsoft\Exchange Server\bin. |
