Hi all, I have the following function that I execute from a service
running on
win2003 terminal server. This code creates a process in a client's
terminal session. I got this to work on win 2000 server. But when I
run in 2003 I always
keep getting ERROR_INVALID_PARAMETER from the function
CreateProcessAsUserW .
I verified the code and every thing seems right. I am trying to create
some thing as simple as c:\w2k3\notepad.exe and it still gives this
error. Any body with ideas please help me out

int createTSProcess(char* userName,char* domain,char* passwd,char*
commandStr,char* processDir,long sessionId){
    HANDLE hToken;
    PROCESS_INFORMATION pi;
    STARTUPINFOW si;
    LPVOID lpEnvironment = NULL;

    // initialize STARTUPINFO structure
    ZeroMemory(&si, sizeof(STARTUPINFO));
    si.cb = sizeof(STARTUPINFO);
    __try {
        // obtain an access token for the given user
        if (!LogonUser(userName,domain,passwd,LOGON32_LOGON_INTERACTIVE,LOGON32_PROVIDER_DEFAULT,&hToken))
{
            showError("LogonUser:");
            return FAILURE_AUTH_FAILURE;
        }

        if(EnableSecurityRights(SE_TCB_NAME, TRUE) != ERROR_SUCCESS) {

        }
        //cout<<"Successfully enabled priveleges\n";

        DWORD dwSessionId = sessionId;
