There seems to be a lot of these Event ID: 1000 errors out there, the only thing that seems to be the same throughout is that the issue is an application faulting on a 64 bit system. In our case it is with an application dealing with printing on 3 Remote Desktop Hosts in a Load Balanced Remote Desktop Farm on Server 2008 R2 that we just recently deployed. Does anyone have any insight into what might be causing these Events or possibly even more specific to my situation with Tricerat Screwdrivers version 4.7.00.1. Not really sure what to do about this issue and it is causing a lot of issues for our customers.
