Re: VPN equals slow network folder access

Do not change the [VPN]default gateway, but try eliminate the name
resolution issue by using the IP address of your [work]file server when
mapping the file share. ex. \\10.25.xx.xx\share
Can you successfully ping your [work] file server? 1. by name 2. by ip
address. What are the average RTT times?

The settings are different between direct connection at work and VPN
connection from home.

At work I have a 10.25.xx.xx DHCP address. The default gateway is also a
10.25.xx.xx. There are two DNS servers: 10.20.xx.xx and 10.30.xx.xx. The
primary and secondary WINS servers are the same as the DNS servers.

At home the VPN has a fixed 10.0.xx.xx address. The default gateway is the
same address. There are two DNS servers, both 192.168.0.xx. These are also
the WINS servers. I did change the Netbios option from the automatic
option.

I deleted the shortcuts you suggested. Pressing F5 in My Network Places
finished immediately- no hangs. None of these improved the situation.

I then added in the default gateway and DNS/WINS servers that are used at
work and made sure they were first in the appropriate list. This has
improved
the situation. Opening the mapped folder I normally access now takes 20-30
seconds vs. the 1-2 minutes it was previously taking. Another, larger
mapped
folder takes about a minute vs. the up to 5 minutes it was taking
previously.

Hmmm,
My first suspicion here was name resolution, at home - have you checked
that
name servers for DNS and WINS are set correctly (compare with office
settings. Use ipconfig/all). Make sure Netbios is enabled for your VPN
connection (WINS tab in TCP/IP Advanced properties).

Then, try deleting all shortcuts in "%userprofile%\Application
Data\Microsoft\Office\Recent" folder, this will impact Open/SaveAs
dialogue
boxes when shortcut reference unavailable targets. At last try refresh
(F5)
in "My Network Places" and look for "hang" on any shortcut's here, delete
"hanging" shortcut (right click/delete; may take loooong time before
pop-up
appear)

Actually it does happen with mapped drives as well as UNC paths.

Hi Jerry,

If name resolution works, have a look at this KB "You experience
significant delays when you use network shortcuts on a computer that
is
running Windows XP SP2"
http://support.microsoft.com/kb/918204

Significant impact on slow links, fast links with network "latency"
and
obvious VPN through broadband connections. Measurement (here) by
"Netmon"
shows an improvement as high as 18:1.

Regards,
Rune.
P.S. Mapped network drives do not experience this delay.

I did have to reduce the MTU from 1472 to 1272. Neither that nor any
of
the
other suggestions on that site seem to have made a difference. Any
other
suggestionss?

I have a work laptop running XP Pro. When I'm at work access to
our
internal
network is fine- no more than several seconds to open any folder
on
our
network.

At home I connect the laptop to my 1.5M DSL connection via
ethernet
cable.
Once booted I use VPN to connect to the work network. Local work
on
my PC
operates as normal, no slow down. Outlook is a bit slower, but
acceptable,
when retrieving and opening mail which i attribute to the
connection
being
slower than the internal work network. Likewise Internet Explorer
is
a bit
slower on intranet sights. But opening any internal network folder
literally
takes minutes instead of seconds. During that time all Explorer
windows are
essentially locked up.

What's causing the delay? My IT department just blames it on "the
Internet"
out I don't understand how. I've watched the network connection
with
perfmon
and don't see any noticeable increase in traffic except for a very
small
spike when I first double click the folder. Is there really that
much
traffic
when opening a folder that the combination of the slower internect
connection
and internet vagueries can affect times on the order of 50-100
times
or more?
