To be fair, I think this would baffle Tier 4, 5, and 6. Sometimes I think we are too tough are support. They mainly know AC backwards and forwards and installation on the main computer.
This is a lot of computers on a different type of network. They would have to remote into a few machines. There has been a version change from a version 6 to 7. I think this is an issue for Indy or Sandeep or maybe change to one domain controller and run all machines on the domain. Client/Server on a network domain. Run AC and SQL and PM all on one machine. There are businesses that run different servers for each, but those generally have 50 or more computers and still run on the same network.
Just my thoughts.
