Automatic DCOM Configuration Tool
Download the following automated tools here.
1. Dcpinst.exe is an installation setup for the automated DCOM configuration object. This needs to be run first and only once.
2. QODBCSetDCOM.VBS is a VB script that uses the installed configuration object to setup the DCOM Servers. It will reset and automatically add all necessary security each time it is run. The script can be edited if you need to change the Accounts it is configuring.
3. The new settings will not take affect until the DCOM servers (qbXMLRPeInteractive.exe and qbXMLRP2eInteractive.exe) are removed from memory. Rebooting is the simplest way to accomplish this, but running the Windows Task Manager and Ending Process on any running copies will also work.
