David, a graphic designer working for a small Internet firm, wants to use his own legacy scanner with a new Windows XP Professional system. A Standard PC HAL was installed during the machine build process. David’s computer is a member of the corporate domain, and David has been granted local administrator rights by the Domain Administrator to allow him to customize the setup of his new machine. The scanner requires the installation of a proprietary SCSI card. This card must utilize a specific IRQ setting in order to be recognized by the legacy software application that interfaces with the scanner. David installs the card without incident and reboots his computer, logging on with his own credentials. The card is recognized, but Windows reports a problem during installation. David consults the Device Manager and finds that the IRQ setting required by the card is in use by another device. David attempts to use the Device Manager to reallocate the IRQ resources manually, but finds that the option to do so is grayed-out and unavailable to him. Which of the following is likely to be the problem?
