Nick Khyl 1478028591 docs/windows/policy: use a separate value to track the configuration state of EnableDNSRegistration
Policy editors, such as gpedit.msc and gpme.msc, rely on both the presence and the value of the
registry value to determine whether a policy is enabled. Unless an enabledValue is specified
explicitly, it defaults to REG_DWORD 1.

Therefore, we cannot rely on the same registry value to track the policy configuration state when
it is already used by a policy option, such as a dropdown. Otherwise, while the policy setting
will be written and function correctly, it will appear as Not Configured in the policy editor
due to the value mismatch (for example, REG_SZ "always" vs REG_DWORD 1).

In this PR, we update the DNSRegistration policy setting to use the DNSRegistrationConfigured
registry value for tracking. This change has no effect on the client side and exists solely to
satisfy ADMX and policy editor requirements.

Private WireGuard® networks made easy

Overview

This repository contains the majority of Tailscale's open source code. Notably, it includes the tailscaled daemon and the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows, macOS, and to varying degrees on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.

Other Tailscale repos of note:

For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.

Using

We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.

Other clients

The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.

Building

We always require the latest Go release, currently Go 1.25. (While we build releases with our Go fork, its use is not required.)

go install tailscale.com/cmd/tailscale{,d}

If you're packaging Tailscale for distribution, use build_dist.sh instead, to burn commit IDs and version info into the binaries:

./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled

If your distro has conventions that preclude the use of build_dist.sh, please do the equivalent of what it does in your distro's way, so that bug reports contain useful version information.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.

Contributing

PRs welcome! But please file bugs. Commit messages should reference bugs.

We require Developer Certificate of Origin Signed-off-by lines in commits.

See commit-messages.md (or skim git log) for our commit message style.
