Just found that you get this error “Failed to create empty document” when you attempt to open the Arcserve Brightstor Manager when using Remote Desktop connection to your server after installing Internet Explorer 7.0. Computer Associates have a knowledge base article here but basically :
1. Shutdown the Brightstor Manager
2. Rename the file psapi.dll located in :\program files\ca\brighstor arcserve backup to psapi.dll.org
3. Restart the Brightstor Manager
Simple eh ?
