Here is your answer, Microsoft changed the way webdav and other files are uploaded,
Office 2010 upload manager is designed to work with Sharepoint 2010 not reverse.
But this is how you fix the tool to work with Sharepoint 2007.
IIS 6.0 Do this
Go to the site on each server if you are a farmed environment.
Locate the Web Application supporting the site and add a custom header to the site.
Add the primary url of the site into the custom headers,
http://site.name.com
and click ok.
No need to restart IIS and it will not impact your services. 
IIS 7.0 do this
To resolve the issue, perform the following procedure:
Go to Resource Policies > Web >
Rewriting > Custom Headers > (if 'Custom Headers' is not visible, click
Customize on the right top to enable the view).
Create a new policy with the Resource as <fully qualified domain name of the SharePoint server:*/*> (for example https://sharepoint.juniper.net:*/* ).
Create the action as Allow Custom Headers.
Apply the settings to the required roles.
Note: - This does not interrupt any functionality of the same server, as it just allows Custom Headers, if any, for any request towards this server.
