Folks there is an easy way to restore the sulfnbk.exe file back to where it was. I had the file restored in less than 5 minutes...It took me alot longer to figure out how to fix the dang problem than it did to restore the file. Sincere apologies and please have your windows installation disk ready. Directions: 1. Go to Start 2. Click on Programs 3. Click on Accessories 4. Click on System Information 5. Click on Tools at top of box 6. Click System File Checker 7. A box will have 2 selections...tick on the single file extraction and type in sulfnbk.exe then click OK or Start...insert your windows installation disk 8. Another box will come up so type in Windows System Directory in the "Restore from" line 9. In the next empty line click on Browse and click on the drive that it is being extracted from...drive for cd...mine has the disk drive lit up. 10. File restored
