# WHATPORT(2701)

## NAME

port 2701 — SCCM/SMS Remote Control — Microsoft Configuration Manager remote control — an admin can take over this desktop.

Protocol: TCP  
IANA: sms-rcinfo

## DESCRIPTION

Microsoft's own port table for Configuration Manager lists TCP 2701 for "Remote Control (control)" from the ConfigMgr console to a client. The listener is CmRcService.exe, the remote control agent installed with the ConfigMgr (formerly SMS) client, and it authenticates the admin with Kerberos, falling back to NTLM. A 2701 on a scan is a reliable marker of a domain-joined, ConfigMgr-managed Windows endpoint.

## EXPOSURE

**Do not expose.** This is a screen-and-keyboard takeover channel for managed desktops; it belongs on an internal management network, never on a public interface.

## CHECK

```sh
nc -vz -w 3 TARGET 2701
```
