建立临时 Windows 管理员账户

Create a Temporary Windows Administrator Account

如果需要确认网络共享问题是否与当前 Windows 用户权限、Profile 或 Credentials 有关，可以建立一个临时管理员账户进行测试。

If you need to determine whether the network share problem is related to the current Windows user’s permissions, profile, or credentials, create a temporary administrator account for testing.

1. 以管理员身份打开 CMD

1. Open CMD as Administrator

点击：

Click:

Start → 搜索 CMD → 右键 → Run as administrator

2. 建立测试用户

2. Create a Test User

执行：

net user /add Test mypass

成功后通常会显示：

The command completed successfully.

3. 加入 Administrators 群组

3. Add the User to the Administrators Group

执行：

net localgroup administrators Test /add

成功后通常会显示：

The command completed successfully.

4. 确认用户是否已经建立

4. Verify the User

执行：

net user Test

确认用户存在。

Confirm that the user exists.

也可以检查管理员群组：

You can also check the Administrators group:

net localgroup administrators

应该可以看到：

Test

5. 使用 Test 用户登录

5. Sign in Using the Test User

注销当前 Windows 用户：

Sign out from the current Windows user:

Start → Account → Sign out

然后使用：

Username: Test
Password: mypass

6. 测试网络共享

6. Test the Network Share

Press:

Win + R

输入：

\\192.168.0.123\ShareName

或者实际的服务器共享路径：

Or the actual server share path:

\\SERVERNAME\ShareName

测试结果判断

Interpreting the Result

如果 Test 用户可以访问：

如果 Test user can access the share:

→ 问题很可能与原来的 Windows 用户 Profile、Credentials、权限或用户相关设置有关。

→ The problem is likely related to the original user’s profile, credentials, permissions, or user-specific settings.

如果 Test 用户也无法访问：

如果 Test user also cannot access the share:

→ 问题比较可能在 SMB、Network、Firewall、Server/NAS、Group Policy 或 Authentication 层面。

→ The problem is more likely related to SMB, network, firewall, Server/NAS, Group Policy, or authentication.

7. 测试完成后删除临时账户

7. Remove the Temporary Account After Testing

测试完成后，建议删除 Test 用户：

After testing, remove the temporary Test account:

net user Test /delete

确认：

net user

确保 Test 已经不存在。

Confirm that Test no longer appears in the user list.

⚠️ 安全注意事项 / Security Note

不要长期保留这个测试账户，尤其不要使用简单密码，例如：

mypass
123456
password

Do not keep the temporary account permanently, especially with a weak password.

测试完成后应立即删除。

Delete the account immediately after troubleshooting is completed.
