You can use the Samba **`rpcclient`** utility to interact with **RPC endpoints via named pipes**. The following lists commands that you can issue to SAMR, LSARPC, and LSARPC-DS interfaces upon **establishing** a **SMB session** (often requiring credentials).

#### Server Info

* **Server Info**: `srvinfo`

#### Users enumeration

* **List users**: `querydispinfo` and `enumdomusers`
* **Get user details**: `queryuser <0xrid>`
* **Get user groups**: `queryusergroups <0xrid>`
* **GET SID of a user**: `lookupnames <username>`
* **Get users aliases**: `queryuseraliases [builtin|domain] <sid>`

```bash
# Brute-Force users RIDs
for i in $(seq 500 1100); do
    rpcclient -N -U "" 10.129.14.128 -c "queryuser 0x$(printf '%x\n' $i)" | grep "User Name\|user_rid\|group_rid" && echo "";
done

# You can also use samrdump.py for this purpose
```

#### Groups enumeration

* **List groups**: `enumdomgroups`
* **Get group details**: `querygroup <0xrid>`
* **Get group members**: `querygroupmem <0xrid>`

#### Aliasgroups enumeration

* **List alias**: `enumalsgroups <builtin|domain>`
* **Get members**: `queryaliasmem builtin|domain <0xrid>`

#### Domains enumeration

* **List domains**: `enumdomains`
* **Get SID**: `lsaquery`
* **Domain info**: `querydominfo`

#### Shares enumeration

* **Enumerate all available shares**: `netshareenumall`
* **Info about a share**: `netsharegetinfo <share>`

#### More SIDs

* **Find SIDs by name**: `lookupnames <username>`
* **Find more SIDs**: `lsaenumsid`
* **RID cycling (check more SIDs)**: `lookupsids <sid>`
