date and time sync failed

The problem is that the source `w32tm /query /source` is pointing to the Local CMOS clock and the configuration `w32tm /query /configuration` shows a broken `NtpServer` pointing to a Policy instead of Local

```

Type: NTP (Policy)

NtpServer: ,0x1 (Policy)

```

No matter what I tried (including overriding the registry `SpecialPollTimeRemaining` key, it would always reset back to CMOS and the broken `NtpServer`.

The solution I eventually found was to create a group policy using gpedit.msc under `Computer Configuration -> Administrative Templates -> System -> Windows Time Service -> Time Providers -> Configure Windows NTP Client`

- Enable this policy
- Set the NtpServer to time.windows.com,0x9
- Set the Type to NTP

Save it, run `gpupdate` from Run to apply the policy.

Now you should see `w32tm /query /configuration` show

```

Type: NTP (Policy)

NtpServer: time.windows.com,0x9 (Policy)

```

Once it shows this, go back into `gpedit.msc` and set the `Configure Windows NTP Client` to `Not configured`, re-run `gpupdate` to apply the new policy and now when you run `w32tm /query /configuration` it should show you the correct information

```

Type: NTP (Local)

NtpServer: time.windows.com (Local)

```

and when you run `w32tm /query /source` it should show you

```

time.windows.com,0x9

```

This was the only way I could reset windows time to use a NTP server correctly
