How can I connect to an MS Access database on a separate box using FME Server running as service account? I have granted access to the to the folder to the Service Account but FME doesn't seem to like the UNC path.

First, thanks for getting back to me, appreciate it! I had seen the referenced article, but I don't want to change the account for all items, I'm looking more to maybe impersonate a user for this one workspace to run under. FYI, our Network administrator set up FME Server to run under a service account and they don't want to change this.

As @virtualcitymatt​ said, the way to get this to work is to have the engines running as the same windows service account as the core and application sever.

I imagine the only way to make seperate workbenches run as seperate accounts would be to implement a distributed FME Server Install with an engine on a seperate machine that is then running as the specified account you want. Then make use of queues to route specific jobs to that other engine.
