Good day,

I am running an application (BMSI) that is built on the AdvantageDatabase
server. I have a VPN setup on the Windows 2003 server that houses the
AdvantageDatabase application. I can connect to the VPN, and start the BMSI
application without problems.

The clients connect through the VPN over DSL, 768 Kbps. Most of the time,
the response is acceptable, but not as speedy as I thought it would be. One
particular machine seems to slow things to a crawl when it connects. This
machine can take 2 hours to print a fairly simple report. This machine is
an older computer, but upgraded to Windows XP. The other clients are new
Windows XP machines.

The Windows 2003 server is a Dell, with a Xeon 3 GHz processor, 1 GB RAM,
RAID-5 hard drives.

Where should I look to help improve the speed and responsiveness of the
server? I have the Performance Monitor loaded, with the RAS Total being
monitored. What else should I be looking for?

Thanks.

it could be that the packets on the network get fragmented. I'd try
with following entry in the ads.ini file:

[settings]
packet_size=512

What you also could do is to use compression.
