Browsing in SharePoint slow when opened with Windows explorer

SharePoint slow Problem

Do you experience slow browsing when you open your SharePoint site in your explorer? or you made a network connection to your SharePoint site (explained here).  I sometimes experience this problem with clients where everything was working fine. but one day it just stopped working correctly. When you open a site you might experience a long waiting time, ore even a “Not responding” screen. every time i had this problem it was resolved by disabling one check box.

This check box can be found in “Internet Options > Connections > LAN Settings” and disable the check box by “Automatically detect Settings”. this issue seems to be related to the “WebDAV” protocol and the “Automatically detect settings” conflicting with each other.

Automaticly Detect SharePoint Slow

Solution not working?

In some cases i came across, disabling this check box did not resolve the problem. this could be when another program is interfering with your WebDAV internet traffic. first thing you should look at is your anti virus. if that does not solve your problem you could have a look at the following Wikipedia article: WebDAVWhen you read this you might know what to look for. or what could still be slowing up your SharePoint Connection. If you have any questions, just ask them and i can see if i can help.

    Thanks Ken. As far as I’m concerned the upload speed is still not great on my 2 Mbps-up Internet circuit, but this fix has shot me up from 2-4 Kbps up to as much as 100 Kbps. Last night a 75 MB folder took over 4 hours to upload, this morning I did a 25 MB folder in about 5 minutes. Not perfect, but considering I have another 2 GB to upload today, this should certainly help.

    I’m not sure how the checkbox got checked, but your solution worked for me. Thanks.

      Hi Ken,
      Well it is a default option, but for some users this messed up the browsing speed in Explorer.

    Hi Pieter,

    I have been using SharePoint 2010 at work and I have been experiencing the same slow-down issue for quite a while, i.e. over a month. It’s been really frustrating for me to wait 15 seconds to open folders and sub folders.

    I called IT a couple of times and they could not do anything but disabled the power-saving option for the network card and cleaned my disk with the system tool… No improvement at all despite I have spent over 1 hour with them.

    Then I decided to do some research on my own and I am very glad I found your post and your solution worked just fine. It took me 10 seconds to do it myself with your instructions.

    I am very thankful and you have my sincere appreciation.

    Best regards,
