Okay, some details, because I know this question has been asked several times, but none of the fixes have resolved my issue.
We have a web application that leverages SSRS as its reporting platform. This application uses a Windows AD user as IIS passthrough to connect the application server to the database server (where SSRS is also installed).
We have an embeddable/installable barcode font our SSRS reports are using, and it is showing up on the application server, but nowhere else.
The font has been installed and unblocked on the database and application servers for the IIS passthrough user, as well as for the individual users on their workstations, but the font still doesn't show up on workstations in SSRS's report viewer or when exported to PDF. They show up when exported to Word, but with Word being what it is, that results in none of the labels printing correctly.
Edit: Also, the passthrough user has been granted full control of the font on each server. We've restarted the reporting server service as well.
Edit 2: Well, since the "community experts" here seem in the business of providing a minimalist answer with no follow-up, I should mention that sometimes an "embeddable" font can apparently be a bad thing. We've been able to get restricted barcodes to show where embeddable ones failed.
