I use mRemote to log onto my servers and noticed I repeatedly recieved the following error when logging on:
Please note that I’m actually not experiencing slow log on in any shape or form, I’m just bothered by the warning in my eventviewer.
Remote Desktop Services has taken too long to load the user configuration from server <SERVER> for user <USERNAME>
Here for your issue providing some workaround, might this helpful.
Add a new DWORD (32-bit) Value in registry, name it as “DisableTaskOffload” and set value data to 1 on below mention path.
Also you can try “Get-NetOffloadGlobalSetting “command, which includes Receive Side Scaling, Receive Segment Coalescing, task offload, and NetworkDirect.
Apart from that refer “Troubleshooting Slow Logons” article.
