It feels strange that I can connect it with ActiveSync. Search on MSDN (http://support.microsoft.com/default.aspx?scid=kb;en-us;816826)
The original text is as follows:

These symptoms indicate a possible corrupted the security key container.

On the computer it running Visual Studio. NET, run the DelDesktopCryptKey.exe utility from the command prompt to Clea n the security key container for the current user.

NET 2003\compactframeworksdk\wince utilities\ Deldesktopcryptkey directory to run DelDesktopCryptKey.exe, and then restart the computer, the problem is resolved.
