Hi Server is W2K Advanced SP3. MF is XP FR2 When a user attempts to login using nfuse, he can login, gets the web based program neiborhood, but when he attempts to launch an application he gets an ie file download dialog box stating that the file launch.asp from the server has been chosen for download, and you are prompted with either to open from location or download it locally. Any ideas please Thanks Sinead ******************************************************** This Week's Sponsor - Emergent Online EOL's Universal Printer new Features include: Network Printing, Pagestreaming, 2400 DPI.
