slow file browsing over VPN Windows XP to Windows Server 2003

[thommes_thomassen]

Hi, all!

I experience slow network browsing on a Windows XP client to shared
folders on Windows Server 2003 via VPN.

ping doesn't work.

remote desktop connection works good
synchronising works good

=========
From: http://www.chicagotech.net/vpnslow.htm
2. Use TCP/IP only.
Symptom 4: Browsing some shared folders is normal while others is very
slow.
Cause: If the folder has too many subfolders and files, browsing may
be slow.
Symptom 5: The download is very slow on VPN client after establishing
the VPN.
Cause: The VPN Client may use the remote network gateway.
Suggestion: Change the default gateway from remote to local. To do
this, go to properties of the VPN connection>Properties of TCP/
IP>Advanced, uncheck Use default gateway on remote network.
========

All this didn't help. Is there a way to increase speed for network
browsing? Especially folder and file browsing?
Why doesn't ping work? Any ideas?

Best regards
Thommes

It's not unusual for a server (particularly a secured server) to
disable response to pings. If you can communicate at all with the
server, don't worry about this.

You might want to check your network MTU setting. VPN adds extra
header bytes to each packet and if this causes the overall size of the
packet to get too big for the network, the packet is fractured and sent
in pieces which often causes slow network performance, even failures,
when transferring big packets. Read the FAQ here:

<http://www.dslreports.com/faq/tweaks/4._MTU>

1300 is an extremely conservative value for MTU -- you might want to
try this setting as a test and see if it helps. (That's what Cisco uses
for their VPN Clients).

HTH,
