Re: VPN equals slow network folder access

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?

It could be the computer browser and name resolution issue too. You may try to browse it using the IP instead of the name. Also even the DSL line can be 1.5 MB, the upload may be less than 1MB. This search result may help too.

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?
