Tanium Patch – Remediation Scripts

Tanium Patch – Scripts

A collection of remediation and automation snippets used for fixing Patch issues on endpoints.

These scripts support troubleshooting findings from:

• Patch – Coverage Status Details

• Patch – Scan Age

• Patch – Scan Errors

• Patch – Is Process Running

• Endpoint Configuration – Tools Status Details contains patch

---

1. Windows Remediation Scripts

---

1.1 Restart Tanium Client (Fix stale scans or [no results])

Use when:

• Patch process is not running

• Scan Age = stale

• Scan Errors not returning

• Coverage Status = Needs Attention

# Restart Tanium Client on Windows

$svcNames = @('TaniumClient','Tanium Client')

foreach ($name in $svcNames) {
    $svc = Get-Service -Name $name -ErrorAction SilentlyContinue
    if ($svc) {
        Write-Host "Restarting service: $($svc.Name)"
        Restart-Service -Name $svc.Name -Force -ErrorAction Stop
    }
}

1.2 Force Patch Tools Redeploy (tools missing or corrupt)

Use when:

• Tools Status = [no results]

• Patch engine not running

• Coverage: Needs Attention due to tool issues

# Force redeploy Patch Tools by removing the local tools directory

$patchToolsPath = "C:\Program Files (x86)\Tanium\Tanium Client\Tools\Patch"

if (Test-Path $patchToolsPath) {
    Write-Host "Stopping Tanium Client..."
    Stop-Service -Name 'TaniumClient'Tanium Client' -ErrorAction SilentlyContinue

    Write-Host "Removing Patch tools directory..."
    Remove-Item -Path $patchToolsPath -Recurse -Force

    Write-Host "Starting Tanium Client..."
    Start-Service -Name 'TaniumClient'Tanium Client'

    Write-Host "Patch tools removed. Tanium will redeploy automatically."
}
else {
    Write-Host "Patch tools directory not found: $patchToolsPath"
}

1.3 WMI Verification & Repair (fix scan errors on Windows)

Use when:

• Scan Errors indicate WMI or inventory issues

• Scan Age will not refresh

# Verify & salvage WMI repository

Write-Host "Verifying WMI repository..."
winmgmt /verifyrepository

Write-Host "Attempting to salvage repository..."
winmgmt /salvagerepository

⚠️ Important:
Use winmgmt /resetrepository Only under change-control—it resets WMI completely.

1.4 Endpoint Network Connectivity Check (catalog download issues)

Use when:

• Scan Errors indicate catalog download problems

• Patch Tools keep failing to initialize

# Adjust hostname to your environment
$taniumServer = "tanium.domain.com"

Test-Connection -ComputerName $taniumServer -Count 4
Test-NetConnection -ComputerName $taniumServer -Port 17472

1.5 Windows Quick Patch Health Check Script (single endpoint)

Ideal for hands-on triage of a single problematic device.

# Tanium Patch Quick Health Check – Windows

$results = [ordered]@{}

# Service status
$svc = Get-Service -Name 'TaniumClient'Tanium Client' -ErrorAction SilentlyContinue
$results["TaniumClientService"] = $svc.Status

# Patch tools folder exists?
$patchToolsPath = "C:\Program Files (x86)\Tanium\Tanium Client\Tools\Patch"
$results["PatchToolsExists"] = Test-Path $patchToolsPath

# Free disk space
$sysDrive = Get-PSDrive -Name C
$results["FreeSpaceGB"] = [math]::Round($sysDrive.Free/1GB,2)

# Network to Tanium Server
$taniumServer = "tanium.domain.com"
$results["CanPingServer"] = Test-Connection -ComputerName $taniumServer -Count 1 -Quiet

$results

2. Linux Remediation Scripts

---

2.1 Restart Tanium Client on Linux

Useful when:

• Patch process not running

• Coverage = Needs Attention

• Scan Age too old

#!/bin/bash

echo "Restarting Tanium Client..."
sudo systemctl restart taniumclient.service

echo "Checking status..."
sudo systemctl status taniumclient.service

2.2 Force Patch Tools Redeploy on Linux

Use when Linux endpoint is returning:

• Tools Status = [no results]

• Patch engine never starts

#!/bin/bash

TOOLS_DIR="/opt/Tanium/TaniumClient/Tools/Patch"

if [ -d "$TOOLS_DIR" ]; then
  echo "Stopping Tanium Client..."
  sudo systemctl stop taniumclient.service

  echo "Removing Patch tools directory..."
  sudo rm -rf "$TOOLS_DIR"

  echo "Starting Tanium Client..."
  sudo systemctl start taniumclient.service

  echo "Patch tools removed. Tanium will redeploy automatically."
else
  echo "Patch tools directory not found."
