problems importing Excel 2007 table into SharePoint 2003
 

I am trying to get a 2007 Excel table into our SP2003 Web Services based
Intranet. when I use the Import from SharePoint option I get Method 'Post'
of object IOWSPostData' failed. When I use the Export from Excel option I
get cannot connect to server at this time. Your table cannot be published. I
have checked permissions etc and there is nothing obvious there.

Can any one suggest a solution please.
