There are a variety of reasons that you can receive this message, so if you can get any of the inner error messages or error codes it would greatly help.

You also noted that you are using the device emulator; have you verified network connectivity with the emulator? (Open IE on the emulator and put in the URL to the IIS box and see if can connect)

Also, what versions of IIS and SQL Server/SQL CE are you using?

Okay; made some revisions. Now the error says, "A request to send data to
the computer running IIS has failed. For more information, see HRESULT."

Hi,

Thanks for responding. Amit set me straight on the Mobile directory for the
mobile database. I revised the code and when I first run my Synchronize
method, it copied the database to the My Documents folder in the device
emulator. So, it's apparently where it should be right now.

After that, this IIS error comes up in the device emulator. Details of the
error says it's a NullReferenceException originating from my synchronization
code.

I looked at the Event Viewer (as you suggested) and the latest log that has
a warning has a "Userenv" source. The information on this event states,
"Windows saved user ServerName\userName registry while an application or
service was still using the registry during log off. The memory used by the
user's registry has not been freed. The registry will be unloaded when it is
no longer in use.

This is often caused by services running as a user account, try configuring
the services to run in either the LocalService or NetworkService account."

I don't know what this is about or how to correct this. Thank you for any
help.

Marilyn
