I have a customer running Std Server 2003 with about 15 workstations on a 10/100 ethernet network with two wireless access points. Users are experiencing intermittent performance issues. when performance is impacted it seems to be general. Affects all users, affects Internet page loads, and Server based apps. I have looked at server performance during periods of poor performance using Windows task manager and Process Explorer. Processor Idle time is high and memory utilization seems to be about 50%. The server memory is only DDR2 8GB on Intel S5000 series board at this time. Internet speed tests run during poor performance indicate 30 X 5. Router is Sonic Wall TZ105. I looked for scheduled tasks, scheduled updates, malware scans, etc. but everything is scheduled to run after hours. Quick Books data protect (a resource pig) is disabled.
