结果一同步就报告：
关键性通信服务启动失败，请尝试重置移动设备，然后重新连接
网上找到的资料要不就是说防火墙问题，要不就是说
4: 出现“关键性通信服务启动失败。请尝试重置移动设备，然后重新连接。”
答：打开ActiveSync的连接窗口：
在[文件]>[连接设置]里，根据你的连接类型（红外或连接线），正确的勾选所有的选项。
具体操作----
1、勾取“允许通过COM端口上的串行电缆或通过红外线端口建立连接”；并在该项目的下拉窗口里选择正确的端口。
2、勾取“允许通过USB端口建立连接”； www.shengfang.org
3、手机里打开的ActiveSync软件中，[服务器设置]里的所有项目都可以不选取，（服务器名称,域, 留空不用填）；
[PC 设置]里，在[使用移动日程安排与此PC同步]项下，取消前面的勾（即确认不要打勾）
4、电脑上打开的的ActiveSync软件窗口中，按[选项]>[同步选项]里，也全部留空。到有需要时再手工同步就行了。

Using ActiveSync Over Virtual Switch
Configure the emulator to use Virtual Switch. For more information, see Changing Ethernet Support in the Emulator .
Start the emulator.
Open the SDK command prompt, found under: Start->All Programs->Microsoft Smartphone SDK->Smartphone SDK.
Run emuascfg specifying the /SP flag for the Smartphone emulator. Press Enter, and wait until emuascfg has completed.
Close the command window when it's finished.
Confirm that ActiveSync has Allow Network (Ethernet) and Remote Access Service (RAS) server connection with this desktop computer enabled. Find this under ActiveSync's Connection Settings dialog.
Switch to the emulator.
Open ActiveSync in the emulator.
Choose "Sync".
The emulator will then connect to the desktop via the ethernet.

EmuASCfg.exe—This tool configures ActiveSync and the Pocket PC emulator to allow establishment of an ActiveSync partnership over the Ethernet Virtual Switch. You must use eMbedded Visual C++ to boot the Pocket PC emulator using the VirtualSwitch option before running this tool. For usage information, type "emuascfg.exe /?" at the command line
a)one option can be  to share a folder and just send it there:

Moving Files to and from the Emulator
Files can be moved to or from the emulator by using any of these methods:

ActiveSync's Explore functionality (for more information, see Using ActiveSync with the Emulator).
The Remote File Viewer tool that is available in eVC 4.0. The Export function moves a file from the file system of the development workstation to the file system of the real or emulated Smartphone device. The Import function moves files from the real or emulated Smartphone device to the development workstation file system.
Sharing the files within the development workstation file system and accessing those files by using the File Manager in the emulated Smartphone image.
