Hiya again Thanks to everyone who mailed to say it is a hoax "chain letter". I do hope you've not deleted the file (as I have!). I'm going to kill my cousin. If you've beaten me to it, this is how you get it back: Windows 98 and Windows 98 Second Edition To extract files in Windows 98 or Windows 98 Second Edition, use the System File Checker tool: 1. Click Start , and then click Run . 2. Type sfc , and then press ENTER. 3. Click Extract one file from installation disk . 4. In the Specify the system file you would like to restore box, type drive :\windows\command\sulfnbk.exe (where drive is the drive on which the Windows folder is installed, usually drive C), and then click Start . The Extract File dialog box is displayed. 5. Next to the Restore from box, click Browse , and then browse to the location of the Windows installation files. If the installation files were copied to the hard disk, this location is C:\Windows\Options\Cabs by default. You can also insert the Windows installation CD-ROM in the CD-ROM or DVD-ROM drive and browse to that location. 6. Click OK , and then follow the instructions. Many apologies for causing trouble - and for being such a dumplin'! Marjie
