Hello, 1) What is the total number of workstations and servers in your office? 2) Which brand of network hardware (routers and switches) are you currently using? 3) Are you using a specific server OS like Windows Server 2022 or a Linux distro? I will stabilize your office IT environment by performing a deep audit of your network hardware and Windows systems to find the root causes of connectivity drops and crashes. I will use a popular endpoint security tool to scan and eliminate all malware and virus infections across your machines. Once the environment is clean, I will harden your security by fine-tuning firewall rules, updating Active Directory group policies, and implementing a reliable backup and recovery plan. I will also deploy a lightweight monitoring service to alert us to performance issues before they cause downtime. I am available to provide direct technical support for all hardware and software needs while maintaining clear documentation of the entire setup. Thanks, Bharat
