On a NW6sp4 server and Imanage 1.2.2, when I manage my broker and try to upload new drivers I get the following error:

HTTP 404-Not Found error

The only option is OK and it's in IE. There is no other message. And the driver upload fails. If I use NWADMIN it will crash. The driver in that case does not upload either. This is all of a sudden. I used to be able to add resources. Any ideas?
