[vpn-help] Windows 7 64bit Slow VPN

I realized that my upload speeds to my office over our VPN were very
slow so I started digging into it. At the office we have a Netscreen 10
hosting our VPN connections. On one of the servers at the office we
have a nice HTTP based file server that I can access remotely using a
public IP address (no vpn) and a local IP address (vpn), and when
uploading it displays KB/Sec. This gives me the ability to compare
upload speeds.
Also, at my remote site (home - Comcast cable), I have several different
machines behind the same router running different OS's. These are the
machines.
Two Windows 7 64 bit machines
One Windows 7 32 bit machine
One Windows Vista 32bit machine
All the machines have Shrewsoft 2.1.7 installed using the same config.
I tested all them without the VPN and they all uploaded at about
550-600KB/sec.
On the Window Vista 32bit machine, I tried both Shrewsoft and my
original Netscreen client. They both performed ok at about
450-500KB/sec. (Slower than without VPN, but I guess that's expected).
Same results as above on the Windows 7 32 bit machine.
However, on both the Windows 7 64bit machines, I'm only getting about
12KB/sec which is painfully slow.
A co-worker at another remote location using Windows 7-64bit and
Shrewsoft 2.1.6 can upload at about 550KB/sec. I uninstalled my 2.1.7
version and installed 2.1.6, but I get the same results, so I don't
think it's 2.1.7.
Can anyone give me some pointers on where to look to figure out why it's
so slow.
Thanks,
Mark
