New constructor NmxClient::create(ntlm_factory) gated on
cfg(all(windows, feature = "windows-com")). New crate feature
mxaccess-nmx/windows-com propagates to mxaccess-rpc/windows-com.
Mirrors ManagedNmxService2Client.Create() (cs:30-64) plus
ResolveService (cs:491-523).
Six-step bring-up:
1. com_objref_provider::marshal_activated_iunknown_objref(
"NmxSvc.NmxService", MarshalContext::DifferentMachine)
activates and emits the OBJREF.
2. ComObjRef::parse extracts oxid + the activated server's IUnknown
IPID.
3. resolve_oxid_with_managed_ntlm_packet_integrity against
127.0.0.1:135 (RPCSS endpoint mapper) returns the server's
(host, port) bindings + IRemUnknown IPID.
4. parse_bracketed_host_port pulls the host + port out of the
ncacn_ip_tcp binding's `host[port]` text. Uses rfind for the
rightmost brackets so FQDN forms (foo.example.com[1234])
round-trip — matches the .NET ParseBracketedHost/Port shape at
cs:540-561.
5. A fresh DceRpcTcpClient binds to IRemUnknown and calls
RemQueryInterface(iunknown_ipid, INmxService2_IID,
fresh_causality_id, public_refs=5).
6. A second fresh transport binds to INmxService2 via Self::connect.
The ntlm_factory: impl FnMut() -> NtlmClientContext closure is
invoked three times (one per bind); each NtlmClientContext is
consumed by its bind, so the factory must produce fresh contexts.
New NmxClientError variants:
- Activation(ProviderError) — only emitted with windows-com on.
- EndpointResolution { reason } — covers no ncacn_ip_tcp binding,
malformed host[port], non-zero RemQueryInterface HRESULT.
6 offline tests on parse_bracketed_host_port: FQDN host extraction,
rfind for rightmost brackets, rejection of missing '[' / missing
']' / non-numeric port / port overflow.
1 live test (#[ignore], gated on MX_LIVE + MX_TEST_USER /
MX_TEST_PASSWORD / MX_TEST_DOMAIN populated by
tools/Setup-LiveProbeEnv.ps1): round-trips the full chain against
the AVEVA install on this host. Resolved INmxService2 IPID is
non-zero — verified end-to-end.
Workspace: mxaccess-nmx 17 → 23 (+6). All other crates unchanged.
Closes F12 in design/followups.md. F6 (ComObjRefProvider port) was
the prior blocker; with both landed, the COM-activation path is
end-to-end functional.
