For small and medium-sized businesses using networked personal computers with a centralised server and communications equipment, Green Light Systems provides comprehensive systems management and support, including the activities described on this page.
Requirements gathering and systems design:  We can provide all the advice and support you need to build an efficient IT infrastructure from scratch, one that meets genuine business objectives.
Hardware and software installation and configuration:  Every modification and addition to a computer system has ramifications. We firmly believe in the need to carefully integrate system changes with existing systems, in order to maintain optimal system performance and avoid negative impacts on the system.
Routine System Administration and Maintenance:  We all know "Prevention is better than cure". A regular system health check, including software and antivirus updates, allows potential problems to be averted or to be diagnosed before symptoms impact users.
Troubleshooting and Problem Resolution:  Our broad-ranging knowledge of networked computer systems allows us to readily identify the source of most problems. We also have access to specialist resources to track down the most subtle and obscure faults.
Antivirus and spyware removal:  Given the interconnectedness of modern computer systems, malicious attacks can rapidly spread across the globe and compromise system integrity. While a well-designed system should minimise such risks, damaging viruses and spyware expolit the vulnerabilities associated with all software. We will always recommend safe practices and secure systems design, but should a system become infected, we can usually remove the malicious software, recover apparently lost data, and apply enhanced security configurations to stop similar attacks.
Performance Tuning:  For all the incredible improvements in computer hardware performance, computer systems are frequently reported as being too slow. To some extent this is a consequence of the ever-more sophisticated demands placed on hardware by modern operating systems and applications software. However, the performance improvements that can be obtained by careful tuning of personal computers and networking systems, can be dramatic.
Systems Audit:  A thorough systems audit is regularly required to assess the current state of existing systems. This allows identification of existing and potential future problems, ensures continuing systems availability, and reduces maintenance costs.
Site Documentation:  Very few smaller organisations possess adequate site documentation. Configuration data sheets for each networked device, and a network topology map, are important deliverables of the systems audit process. Accurate and up to date records are an invaluable aid in reducing systems management effort.
Supplier Liaison:  Computer systems suppliers often request customers to provide detailed and complex descriptions of problems. The availability of a systems expert working on behalf of a client organisation, facilitates efficient problem resolution with third parties.
Sourcing and provision of pricing information:  The rapidly changing nature of the product offerings in the information technology industry requires expert technical and market knowledge, to ensure the best available solutions are being exploited.
