DCE RPC problem in 64bit client on hp-ux 11i with Windows 2000 server

During porting of our system's client side to HP-UX 11.11 platform with installed DCE RPC 1.8 in 64-bit mode (with kernel threads libdcekt.sl) we have problems working with our server on Windows 2000 Server Service Pack 4 ENU or Windows 2003 RTM ENU in 32-bit mode.
Our client library was already ported to hp-ux 11i 32bit, openvms 7.3 64bit, AIX 5L previously.

An error occurred in simple DCE RPC call (something like a Ping without any parameters) by ncacn_ip_tcp protocol (RPC binding ncacn_ip_tcp:[1335]).
Error code is "0x16c9a041:Connection request timed out (dce / rpc)" and corresponds to rpc_s_connect_timed_out. By analyzing network traffic we find that tcp/ip connection is established.

We also verified next configurations for our sample application:

hp-ux 32 bit -> windows 2000/2003 32 bit: works

hp-ux 32 bit -> OpenVMS 7.2 64 bit: works

hp-ux 32 bit -> hp-ux 64 bit: works

hp-ux 64 bit -> OpenVMS 7.2 64 bit: works

Hp-ux 64 bit -> Windows 2000/2003 32 bit: error

Re: DCE RPC problem in 64bit client on hp-ux 11i with Windows 2000 server

Well, let me simplify this question. Does anyone have working example of working from HP-UX 11i 64-bit to Windows Server 2000/2003 32-bit using DCE RPC?
