Problem with CUDA SDK samples CUDA SDK samples can't find Tesla C870

Good day to all.
I have problems with CUDA SDK samples and NVIDIA Tesla C870 card.

I’m trying to run SDK samples, but they can’t find Tesla card.

System configuration: Windows 2003 Server x64 SP2.
CUDA driver beta:
http://www.nvidia.com/object/thankyou.html…(177_35)Int.exe
CUDA Tool Kit 2.0
http://www.nvidia.com/object/thankyou.html…beta2_Win64.exe
CUDA SDK 2.0
http://www.nvidia.com/object/thankyou.html…eta2b_Win64.exe

(these links was received from NVIDIA Customer Care)

In Device Manager all is fine, C870 is detected, there are no visible
problems with device or driver.

But the result of binomialOption SDK sample is next (Release):
x64, Release:
Using single precision…
Using device 0: Device Emulation (CPU) <— ???
Generating input data…
Running GPU binomial tree…
Options count : 512
Time steps : 2048

Comparing the results…

L1 norm: 1.045245E-004
CPU binomial vs. GPU binomial
L1 norm: 1.000000E+000
TEST FAILED
Shutting down…

As I understand, “real” Tesla card wasn’t found.

When I execute this sample under debugger I see next messages in MSVS Output window:
First-chance exception at 0x77d67d8d in binomialOptions.exe: 0x000006BA: The RPC server is unavailable.
First-chance exception at 0x77d67d8d in binomialOptions.exe: 0x000006BA: The RPC server is unavailable.

They appears during call to cudaGetDeviceCount routine.

In “Debug” mode output of this sample is next:
Using single precision…
Using device 0: Device Emulation (CPU)
Cuda error in file ‘.\binomialOptions.cpp’ in line 164 : initialization error. <— call to cudaSetDevice

and also

First-chance exception at 0x77d67d8d in binomialOptions.exe: 0x000006BA: The RPC server is unavailable.
First-chance exception at 0x77d67d8d in binomialOptions.exe: 0x000006BA: The RPC server is unavailable.

First-chance exception at 0x77d4dd10 in binomialOptions.exe: Microsoft C++ exception: cudaError at memory location 0x0012b794…
The program ‘[1584] binomialOptions.exe: Native’ has exited with code 1 (0x1).

in Output window under debugger.

I started to find anything about “The RPC server is unavailable” error
(may be this is not a root of problem, but…).
All problems with this exception I found in MS Knowledge base is about
DCOM or inter-machine communications. I think this is not my case, but
I did all proposed checkes: RPC service is running, firewal is absent.

How can I “bring Tesla card to life” ?

Thank you.
Georgiy.
