Windows Azure Tools DSInit Error

Development Storage始终启动不了，发现默认DSInit初始化失败。于是手动执行DSInit + 命令参数，但是出现如下错误：
Failed to create database ‘DevelopmentStorageDb20090919′ : A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified)

One or more initialization actions failed. The development storage cannot be used without resolving these errors.

我的SQL Serve远程连接是允许的，那应该是实例错误。尝试了如下一些命令全部失败：

DSInit /sqlInstance:.
DSInit /sqlInstance:JUNCHU-PC
DSInit /sqlInstance:JUNCHU-PC\MSSQLSERVER

国外不少论坛都提到了如何解决问题，不过基本是建议重新创建一个名称为SQLEXPRESS的实例或者重新安装SQL SERVER。偶然的情况下发现只要附加/forceCreate参数以上的命令就可以成功执行。命令如下：

DSInit /sqlInstance:. /forceCreate
