Server is low on memory - Need Resolution

Hi there;

I'm new to this forum and only mildly technically inclined. We've had a change in management in our business and as such, we have a gap on IT knowledge. I'm trying to fill in for now.

I'm currently receiving the follow "Reason" on our Symantec Endpoint Protection Manager Real-time Summary Report.

"Server is low on memory."

CPU Usage is 5%

Memory Usage is 99%

Free System Disk Space is 13497mb

Free Data Disk Space is 11415mb

I read on some other articles and have confirmed that the server running this has met the sufficent system requirements.

I'm looking for alternatives in order to assist in correcting the memory issue...in a simple and easy way. :)

Thanks in advance!
