If there is a problem, boot into safe mode and delete it and and d347prt.sys from windows\system32\drivers\, then boot into windows as normal and uninstall daemon tools, restart again, then reinstall daemon tools (if you still want it on)

Scott Dameon tools driver... Almost certain to cause system failure if you play any games or use any software that checks for emulation as they will attempt to stop it.
Richard I have had problems and only since i have installed Deamon tools, safe mode won't load up because of this file and its hard to get back into xp, am guessing because of this file, i would remove it if you have it, i have done and hasn't affected xp nor Deamon tools (it's fixed my problem)

~Cruiser~ Make sure that your d347bus.sys is located in the folder C:\Windows\System32\drivers. It's necessary for Daemon Tools. If you have more than 1 d347bus.sys or it is not where it should be then fix it. It is NOTdangerous when it is the legitimate file.
Daemontools virtual scssi driver
Mike Stickler I've had Daemon Virtual CD Install for two years without problems. I installed a virtual floppy driver and my system started crashing when loading the d347bus.sys. At this point, I do not know if it is a conflict between the two programs or if the virtual floppy program is the whole problem.  See also: Link
ilari This file was left on the machine, and it's still loaded after uninstall. Use special removal tools, if you want to get rid of it. If you are using daemon (brilliant program) u need it.
xantosdude Daemon Tools driver: if you installed windows service pack 2 and are using a ATA HD then it will bluescreen you or make your startup play a loop... to fix, rename that file and sptd.sys... well it worked for me anyways. Either that or you can reinstall windows.it seems like you need it b/c if you didnt it would start-up... windows deems it as a virus i think...
Xantosdude If you have an ATA HD and Windows service pack 2, your comp will either get bluescreened or play a startup loop and never load
TzeDragon Suspect its associated with ZoneAlarm 70_302_000. File prevented XP SP2 from starting. Reinstalled ZA and now it all appears to be working again.
Wizzie daemon tools driver and it may give this error when u disable primary or secondary ide channels
Deamon tool driver for virtual drive. may enter in conflict with other drive and generate errors at start up
Terry I had the same problem as above; Windows wouldn't boot, it was the SCSI Driver of Daemon Tools, only the file name was different, it was dtscsi.sys. So if you can't find the variant d347bus.sys or d347prt.sys, try dtscsi.sys.
Brian Daemon tools driver. Can cause booting trouble. Was able to remove with safe mode, and then boot succesfully.
long_live_dos had to delete it to get my pc back up and running... error while booting after blackout...
Joan Mir When I boot in safe mode considering d347bus.sys, the computer turn off with no posibility of interaction. I have WXP with SP2 and using Demaon Tools... but the problem appear after other software installation. I deleted it, but this file is not the problem. Finally, I have reinstalled the OS
