The description for Event ID ( 27745 ) in Source ( Windows SharePoint Services 3 ) cannot be found问题解决

我检查MOSS2007服务器时，发现LOg中有很多以下错误，几乎是隔几秒钟就出现一次。
The description for Event ID ( 27745 ) in Source ( Windows SharePoint Services 3 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: #50071: Unable to connect to the database SharePoint_Config on SDS439-003.  Check the database connection information and make sure that the database server is running..
但是我的MOSS2007服务器运行基本正常，就是自动审批等工作流不能发送邮件，搜索网上查到以下建议：
Try restarting all of the following services:

Distributed Transaction Coordinator (MSDTC)
Windows SharePoint services Administration
Windows SharePoint Services Search
Windows SharePoint Services Timer
Windows SharePoint Services Tracing
Office SharePoint Server Search(2008/1/23日追加)

我并没有使用MSDTC，所以此项与我无关，但是其中的Windows SharePoint services Administration和Windows SharePoint Services Tracing分别使用的是Local system account和Local service account，将他们换成专用的本地管理员账户，上述问题就解决了，并且收到了没有收到的审批邮件。
不知道其中是否有必然的关联关系。
