I'm using NT4.0 SP6 and ArcServe IT 6.61. I'm receiveing an error during the backup which involves a quickbooks file. The error is E3406 "Unable to read from file" sharing violation. I can manually back the file up with no problems, but during a scheduled back up it is skipped. I have followed the instructions given by CA on checking the permissions, but I'm still receiving this error. Any help would be appreciated.
