How to Reinstall Your Garry's Mod Server

Last updated: May 6, 2026

Whether you've made a mistake in your configuration, encountered corrupted files, or simply want to start fresh, reinstalling your Garry's Mod server restores it to a clean base state. This guide covers a full reinstall through the NolimitHost Game Panel, and explains the difference between a full wipe and a core file restore.

What a Reinstall Does

A reinstall replaces the core Garry's Mod server files with a fresh copy. It is useful when:

  • A core file has become corrupted and the server fails to start.
  • You want to remove all custom addons, configs, and gamemode changes.
  • You've changed game modes or plans and need a clean slate.
Warning: Option 1 below deletes everything on your server — including custom configs, addons, and maps. Back up anything you want to keep before you start.

Option 1 — Full Wipe and Reinstall

This removes everything and gives you a completely fresh server.

  1. Log in to the NolimitHost Game Panel and click on your Garry's Mod server from the dashboard.
  2. Stop the server if it is running — deleting files while the server runs can cause errors.
  3. In the left sidebar, go to Management > File Manager.
  4. Tick the checkbox at the top of the file list to Select All.
  5. Click the Delete button to remove all existing files.
  6. Go to Configuration > Server Actions.
  7. Click Reinstall. The panel will download a fresh copy of the server files.

Option 2 — Core File Restore (Keeps Your Files)

If you only need to repair corrupted core files without wiping your addons, configs, or maps:

  1. Log in to the NolimitHost Game Panel and click on your Garry's Mod server from the dashboard.
  2. Stop the server.
  3. In the left sidebar, go to Configuration > Server Actions.
  4. Click Reinstall without deleting any files first. The panel will restore core files while leaving your existing data in place.

After the Reinstall

Your server comes back with a clean configuration, so you'll need to re-apply your personal settings. server.cfg is the main configuration file for your server, where settings like the hostname and game mode are stored.

  • Re-apply your server.cfg settings (hostname, password, gamemode, etc.).
  • Re-add your Workshop Collection ID in Startup settings.
  • If you reinstalled ULX or other admin mods, re-run the superadmin setup — see How to Set Yourself as Superadmin.
Remember: Once you've re-applied your settings, press Start in the Game Panel to launch your server. Always stop the server before making config changes so it doesn't overwrite them.
