Memory: High Pages/Sec Windows 2000/2003

We just started using GFI server monitoring for the various servers in our network, and we're getting a lot of message alerts regarding processor performance and memory. When viewing the performance monitor on each server, the processor performance will rarely spike and typically is very low. The memory, though, shows a maximum of over 3,000 pages per second and an average of +/- 80. I understand that the pages/sec number should be closer to 20, so I'm just wondering what configurations I can check to make sure everything is optimized. The servers are running SQL server on them, but nothing else besides random file sharing (hardly any at all).

Windows Server 2003 Standard R2 SP2
3.5GB usable RAM (1.7 taken by sqlservr process)
Intel Core2 Duo E4600

Windows Server 2000 SP4
2GB Usable RAM (1.6 taken by sqlservr process)
Intel Xeon 3.0

FYI: There are far more alerts happening on the 2003 servers than on the 2000 ones. I've already tried moving the paging file to another partition without benefit. Adding another drive simply for the effect of reducing these alerts isn't an option, as we don't notice performance decrease. Just the alerts.

Thanks for the article, it was a good read. Everything looks good as far as Kernel memory goes (details below), and there are no system event logs for event 2019 or 2020. Any other suggestions?

Kernel Memory (machine that most recently alerted to memory issues via GFI, a windows server 2003 box)
Paged WS - 32,880
Paged Virtual - 33,372
Paged Limit - 270,336
____________________
Nonpaged - 34,680
Nonpaged Limit - 261,892

Also, my available physical memory on this 2003 box is always at least 1GB. Commit remains constant at 2.2 with a limit of 5.4.

Have you ever worked with paged verses nonpaged pool memory?  I have dealt with issues with pooled memory on both 2000 and 2003, especially if running high memory utilized programs like SQL or Exchange.

Might be a rabbit trail, but it would be worth looking at....

Thanks again, guys. I ended up going with Nagios instead of GFI as it's free and a bit more versatile, and I don't get these messages using Nagios. However, the information you provided was definitely helpfull in trying to understand the issue.
