Hi, Firstly, please make sure that your web application has a “/” root site collection at http://yourservername , if hasn’t, please create a root site collection on the web site. If you are connecting to a SSL/HTTPS site this is a known issue that was recently reported. I am sorry there is no hotfix currently. The workaround is to open a separate Explorer window. Thanks for your understanding. Xue-Mei Chang TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.comXue-Mei Chang

I will try that but the policy is that no root level site collection, this is how they have configure there managed path also (dont know why ) , but I will try to do that and post back. Thanks.

Hi, Would you please let me know current status of your issue? If you need further information, please feel free to let me know. Have a nice day! Xue-Mei Chang TechNet Subscriber Support in forum If you have any feedback on our support, please contact tngfb@microsoft.com Xue-Mei Chang

I'm running into the same issue. We have SharePoint 2010, we force external users to go to https ://sharepoint/. If they try to open document library with explorer it fails, but if stop forcing them from using https and they access http ://sharepoint site they are able to open doc library with explorer.

I found a fix for the issue, users need to follow these instructions http://support.microsoft.com/?id=943280
