安装SQL Server 2005的时候，出现错误，错误对话框的内容没有记录下来，不过Summary.txt（Summary.txt 位于%ProgramFiles%\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix）文件中有如下信息。
Machine : ServerName
Product : Client Components
Error : Failed to install and configure assemblies C:\Program Files\Microsoft SQL Server\90\NotificationServices\9.0.242\Bin\microsoft.sqlserver.notificationservices.dll in the COM+ catalog.
Error: -2146233087
Error message: Unknown error 0x80131501
Error description: The Transaction Manager is not available. (Exception from HRESULT: 0x8004D01B)
微软提供的解决办法如下：
To work around this problem, make sure that the Distributed Transaction Coordinator service runs under the NT AUTHORITY\NetworkService account. To do this, follow these steps:1. Click Start, click Run, type Services.msc, and then click OK.
2. In the Services window, double-click the Distributed Transaction Coordinator service.
3. In the Distributed Transaction Coordinator Properties dialog box, click the Log On tab.
4. On the Log On tab, specify the NT AUTHORITY\NetworkService account to be the logon account if the logon account is not the NT AUTHORITY\NetworkService account.
Note You are prompted to restart the Distributed Transaction Coordinator service if the following conditions are true:• You change the logon account of the Distributed Transaction Coordinator service.
• The Distributed Transaction Coordinator service is running before you change the logon account.
5. Start the Distributed Transaction Coordinator service if it is not started.
但是在启动时如果出错，错误代码为1073337669 的话，在命令提示符里输入
msdtc -resetlog
注:这种错误我只有在安装VS2005时不选择SQL Server组件，后来再安装SQL Server时才出现。
