Let me get this straight...
You are mapping users to "shared drives" over a 768k line, and
YOU ARE WONDERING WHY ITS SLOW???
it would be slow over a T-1!!!!
First, get more bandwidth... cifs & netbios are VERY CHATTY protocols...
more chatty than your girlfriend telling you about her day at work...
They need lots of bandwidth and or a Riverbed appliance to work well on slow
speed wans (i.e. slow speed under 10Mbps), and even then they are not
perfect. On 768K they would be absolutely Les Miserable...
I ran a 50+ site wan with slow speed links using all these services, email,
fs, etc...

Perhaps complete saturation of the line... do your users run limewire, etc.
and download and share mp3's? Time to break out wireshark... here we go
Once we do that, lets look at the setup of this vpn to make sure its good.
Post your configs (hub and site b router) for us. We'll look at.

Hello All,
I have a VPN tunnel between two cisco routers (site A hub side, site B
remote side). The remote side is a 768K DSL line.
Users in site B keep experiencing slowness and loss of connectivity to all
services,(email, network drives, surfing). While troubleshooting, we issue
pings from their machines to the various servers in remote networks. Ping
results are inconsistent. Two pings work, three don't, two don't, three do.
This is true for any windows server in the network.
Pings to any Cisco device from the same user machine work completely. No
packet loss at all.
I have never seen this before. Any idea why this happens?
I have remote connectivity to all devices at site B, it's just slow.
Thanks!
