Troubleshooting Guides​

Windows Server Troubleshooting​

Common Issues and Solutions:

  1. Active Directory Problems:

    Issue: Users cannot log in to domain
    Diagnosis: Check Event Viewer on DC for authentication errors
    Solution: Verify time synchronization, DNS settings, and network connectivity

    Issue: Group Policy not applying
    Diagnosis: Run gpresult /r on client computer
    Solution: Force GP refresh with gpupdate /force, check OU structure

  2. File Sharing Issues:

    Issue: Users cannot access shared folders
    Diagnosis: Check share permissions vs NTFS permissions
    Solution: Verify both share and NTFS permissions are correct

    Issue: Files missing after permission changes
    Diagnosis: Check file ownership and inheritance
    Solution: Reset permissions and verify inheritance is enabled

  3. Service and Performance Problems:

    Issue: Server running slowly
    Diagnosis: Check Performance Monitor for resource usage
    Solution: Identify resource bottlenecks, add resources or optimize services

    Issue: Services not starting
    Diagnosis: Check Service dependencies and Event Logs
    Solution: Start required dependencies first, check service account permissions

Linux System Troubleshooting​

Systematic Troubleshooting Approach:

  1. Boot and System Issues:

    # Check system messages
    dmesg | grep -i error
    journalctl -p err

    # Check disk space and inodes
    df -h
    df -i

    # Check system load and processes
    top
    ps aux | sort -k 3 -nr | head -10

  2. Network Connectivity:

    # Check network interfaces
    ip addr show
    ip route show

    # Test connectivity
    ping -c 4 8.8.8.8
    traceroute google.com

    # Check listening services
    ss -tuln
    netstat -tuln

  3. Service and Application Issues:

    # Check service status
    systemctl status service-name
    systemctl list-failed

    # Check logs
    journalctl -u service-name
    tail -f /var/log/syslog

    # Resource monitoring
    iostat -x 1
    vmstat 1

SCRIPT_AUTHOR="Your Name"
SCRIPT_DATE="$(date +%Y-%m-%d)"

# Configuration
LOG_FILE="/var/log/${SCRIPT_NAME%.sh}.log"
CONFIG_FILE="/etc/${SCRIPT_NAME%.sh}.conf"
LOCK_FILE="/tmp/${SCRIPT_NAME%.sh}.lock"

# Functions
log_message() {
    echo "$(date '+%Y-%m-%d %H:%M:%S') [$SCRIPT_NAME] $1" | tee -a "$LOG_FILE"
}

error_exit() {
    log_message "ERROR: $1"
    cleanup_and_exit 1
}

cleanup_and_exit() {
    rm -f "$LOCK_FILE"
    exit "${1:-0}"
}

# Main script logic
main() {
    log_message "Script started (version $SCRIPT_VERSION)"
    
    # Check for existing lock file
    if [[ -f "$LOCK_FILE" ]]; then
        error_exit "Script is already running (lock file: $LOCK_FILE)"
    fi
    
    # Create lock file
    echo $$ > "$LOCK_FILE"
    
    # Your script logic here...
    
    log_message "Script completed successfully"
    cleanup_and_exit 0
}

# Error handling
trap 'error_exit "Script interrupted by signal"' INT TERM
trap 'cleanup_and_exit' EXIT

# Run main function
main "$@"

Security Best Practices​

Windows Server Security​

  1. Account Security:

    • Implement strong password policies
    • Use service accounts for services
    • Regular password changes for admin accounts
    • Account lockout policies for failed attempts

  2. Access Control:

    • Principle of least privilege
    • Regular permission audits
    • Group-based permission management
    • Separation of duties for admin tasks

  3. System Hardening:

    • Keep systems updated with security patches
    • Disable unnecessary services and features
    • Configure Windows Firewall properly
    • Enable audit logging for security events

Linux Security Hardening​

  1. User and Access Management:

    # Secure user accounts
    passwd -l account_name          # Lock account
    chage -E YYYY-MM-DD username    # Set account expiration
    sudo visudo                     # Configure sudo access

    # SSH security
    # Edit /etc/ssh/sshd_config
    PermitRootLogin no
    PasswordAuthentication no
    AllowUsers username

  2. System Security:

    # Firewall configuration
    ufw enable
    ufw default deny incoming
    ufw allow ssh
    ufw allow 80/tcp

    # File system security
    find / -perm -4000 -type f      # Find SUID files
    chmod 600 /etc/shadow           # Secure password file

  3. Monitoring and Auditing:

    # Install and configure fail2ban
    apt install fail2ban
    systemctl enable fail2ban

    # Log monitoring
    tail -f /var/log/auth.log       # Monitor authentication attempts
    grep "Failed password" /var/log/auth.log | wc -l
