COM Security Problems in Vista Beta 5308 release

    Hello.
    I developed a COM object in Windows Vista Beta 5270 release which registered
    with Sync Center. I used as a model the sample code from Windows Vista SDK.
    It all worked fine until I installed the new 5308 release of Windows Vista.
    Now, the code fails when trying to register the dll.

    This is the sample code that fails:

    hr = CoCreateInstance
    (CLSID_SyncMgr,NULL,CLSCTX_SERVER,IID_ISyncMgrRegister,(LPVOID *)
    &lpSyncMgrRegister);
    if (SUCCEEDED(hr))
    {
    hr = lpSyncMgrRegister->RegisterSyncMgrHandler(CLSID_SyncMgrHandler,
    wszCLSIDDescription,0 /* dwSyncMgrRegisterFlags */);

    AssertSz(SUCCEEDED(hr),"Registration Failed");
    hr = lpSyncMgrRegister->Release();

    }

    The call on lpSyncMgrRegister->RegisterSyncMgrHandler returns
    E_ACCESSDENIED.
    Can anyone give me a clue about what's happening here. I tried the sample
    code provided with the Windows Platform SDK and it works just the same.

    I even tried to use
    hr = CoInitializeSecurity(NULL, -1, NULL, NULL,RPC_C_AUTHN_LEVEL_NONE,
    RPC_C_IMP_LEVEL_IMPERSONATE, NULL,EOAC_NONE, NULL);
    before the code section specified above, but has no effect.

    Thanks and the best regards,

    Paul Chis.
