Thanks for the reply. I have checked registry settings and they seemed to be correct, and Start setting is set to 2 (Automatic). The service is started up once I open Registry Editor from Terminal window, but once I shut down Registry Editor, the service is also shut down. Here are the messages after I shut down Registry Editor: [root@fc6-dev ~]# regedit fixme:advapi:RegisterEventSourceA ((null),"ImgLM"): stub fixme:advapi:RegisterEventSourceW (L"",L"ImgLM"): stub Any ideas? Thanks. Michael
