Trying to open a sharepoint library in Windows Explorer via IE 8 results in the error "your client does not support opening this list with windows explorer"

Question

I am attempting to connect to a Microsoft Sharepoint library, via the "Actions -> Open in Windows Explorer" option from the Sharepoint page.  When I do so, I get the error message "your client does not support opening this list with windows explorer".  In short, I am trying to get the "drag and drop" functionality of a Sharepoint library.
I am running Windows 7 64-bit and IE8.  The target Sharepoint environment is a MOSS 2007 EE.  My Windows "WebClient" service is running, and I have no problem connecting to this exact library via a Windows XP computer running IE8.

Answer 1

Verify that the Webclient is started automatically from the Services.msc
Verify that your Portal is in the Intranet local security zone (You can reach it from Your Internet Explorer Browser Security Tag) if not add it to the list
restart the WebClient service if it's work good
If not you have to create a network share to your portal URL directly not your documents library.
Open Windows Explorer or My Computer from the Windows Start Menu.
From the Tools menu, click Map Network Drive…. A new Map Network Drive window opens.
In the Map Network Drive window, choose an available drive letter from the dropdown list located next to the "Drive:" option. Any drives already mapped will have a shared folder name displayed inside the dropdown list, next to the drive letter.
Type the name of the folder to map wich is in this case your SharePoint Portal URL (Don't include the documents libraries)
Click the "Reconnect at login" checkbox if this network drive should be mapped permanently. Otherwise, this drive will un-map when the user logs out of this computer.
If the remote computer that contains the shared folder requires a different username and password to log in, click the "different user name" hyperlink to enter this information.
Click Finish.
I am looking for a suite method :)
