Issues using the Mobile/Embedded Sample for Step by Step: Build a

[Lakota2k]

I have run through the Step by Step: Building a Mobile Book Catalog about 6
times now. I keep getting the same error message that during the debugging, a
SOAPException error message pops up and tells me that Server was unable to
process request --> Login failed to user "netcf_user"

Then it terminates. As I am fairly new to this stuff, and have no clue what
that means can anyone assist?

I have tried to run a local service as well as the one described in the
example with no different results.

Any assistance would be greatly appreciated.
Thanks,

Lakota
