This is puzzling as it was working yesterday on the same server. Our users were able to work effectively on the same servers except for the cheque alignment problem.

According to the application, Oplocks are disabled, but we are using SMB2 with DFS. We're not doing any replication, but we are using DFS to keep a unified namespace. So far it hasn't caused any troubles. Will moving to SMB1 tangibly impact our system or other applications?
