If anyone is interested I found the issue was with the DOCICON.XML file in the 12 hive... a previous developer had added a tag and not closed it, which seemed to completly break all the file associations. Not a very helpful error message.. and took me half a day to track it down. Blog here about it if anyone wants - http://my-sharepointer.blogspot.com/2009/08/unable-to-open-office-documents-from.html Cheers
