Hi,

We have a HP Proliant DL 320 G3 acting as our firewall and VPN server. It has a 18 SCSI drive a Pentium 3 and 2 Gb of RAM.

We have around 50 people onsite and 7 people offsite working through the VPN. About 40% of the people use the VPN from home in offhours and during the weekend or when outside in meetings.

The remote workers are the ones that are complaining that the VPN is slow. We probably have a bottleneck, but when I quickly check the performance of the machine, there is a 8% of CPU use and 1.34 Gb of memory use.

I would like to know if there is any tool that could assist me in getting a better insight of why the user experience is that the VPN is "slow".

We also would like to have a more fault tolerant approach in this server, so It would be possible to have another "twin" server and use some sort of redundancy.

I forgot, We have ISA Server 2004, I don't know how to check if it is the standard or the enterprise edition. I think We have a new service pack license of ISA Server 2006 if that helps

 Thanks,

 Miguel
