I have absolutely horrible transfer speed on a new gigabit switch with DC Server 2012 R2 running Essentials. I made the following change and rebooted after even forcing a GP update:
Open up Group Policy Editor, and right-click-and-edit Default Domain Controller Policy. Go to Computer Configuration/Policies/Windows Settings/Security Settings/Local Policies/Security Options, and set Domain member: Digitally encrypt or sign secure channel data (always) and Microsoft network server: Digitally sign communications (always) to Disabled.
The server has two GB Nics in bridge mode in the switch, and the lan speeds are horrible: a 95 MB folder is transferring at less than 89 KB, and even slows.
All clients are Windows 7 Pro.
Any other ideas than just this change? Maybe a difference with Server 2012 R2?
One clue: I can pull a 16 GB PST file from a client experiencing this issue with no delay, but if I attempt to send the file it fails. I am using the c$ share on the client. Could this just be wiring in the cable and bad receive pairs?
