Need to improve VPN throughput, possible compression or different set up

Here's the background info.  We have a central office in Cleveland, Ohio, and a remote, two man branch in New York.  Our VPN setup is currently done through Routing and Remote Access on our windows 2000 server, using PPTP, no IPSEC or anything like that.  Users are experiencing slowness and crashes when opening up larger files (4 megs) or saving them.

Would it be better to use a cisco VPN router to handle the VPN traffic?  Would this improve throughput?  Is there a way to compress VPN traffic for faster throughput?  In general, what can be done to improve VPN speed?

it would probably be one of the first things i would look at-is it a site to site tunnel you have set up already?it doesnt have to be cisco,juniper or checkpoint are other ones.the cisco asa is another firewall that would also do the job-also how many users are there on vpn?

Could you explain what you mean by a site to site tunnel please?  The two users in question are renting from an office space in New York which provides internet access.  Then they're using the built in windows xp client to connect.

And they're using a fiber optic line at the two man site for the default gateway which is lightning fast (something ridiculous like 11 mbps).  We have about 5 other users using VPN.

thats ok its remote vpn than they use-site tosite is the other type
actually your solution might be a file  terminal server not a router as it might spped up access

Yeah, we've got a pc here onsite that they can VNC into, the problem is that there's cursor and key entry lag.

Your best bet with remote desktopping using VNC is to reduce the number of colours used by the VNC transport.  Before connecting, click the Options and reduce the number of colours.  Alternatively, once open, right-click the title bar & choose Connection Options to get the same dialogue.
