When you are downloading files using FTP with Windows NT 4.0, you may receive the following error message on a blue screen:


Running Windows NT 4.0 with an incorrect version of the Aic78xx.sys driver for Adaptec SCSI adapters causes this condition to occur intermittently.


Check the time and date stamp and file size of the Aic78xx.sys driver to determine if the correct Windows NT 4.0 version is installed. This driver file is located in Winnt\System32\Drivers folder.
   Aic78xx.sys   27K   8/2/96 1:30 AM

Compare the installed aic78xxx.sys file with the one located on the Windows NT 4.0 CD-ROM and if it is different, replace it.
