# `SMBVersion` enum

GPO policy: "Mandate the minimum version of SMB" under Computer Configuration > Administrative Templates > Network > Lanman Server. Controls the minimum SMB dialect the LanmanServer service will accept from clients. Raising the minimum dialect blocks older, less-secure SMB versions. Registry: HKLM\SOFTWARE\Policies\Microsoft\Windows\LanmanServer:MinSmb2Dialect (REG_DWORD). Note: this policy does not prevent SMB 1 if that component is still installed and enabled separately. Reference: [Detect, enable and disable SMBv1, SMBv2, and SMBv3](https://learn.microsoft.com/en-us/windows-server/storage/file-server/troubleshoot/detect-enable-and-disable-smbv1-v2-v3)

## Values

| Enum Value | Description |
|---|---|
| `SMB_2_0_2` | SMB 2.0.2 minimum (registry value 514 / 0x202). Lowest dialect; allows all SMB2+ clients. |
| `SMB_2_1_0` | SMB 2.1.0 minimum (registry value 528 / 0x210). Blocks SMB 2.0.2-only clients. |
