Scribbles for my bad memory

Problem

• Our IT security team has weird security setup, which successfully prevented the RDP client from remembering the password, and also caused the following annoying issue

  • RDP connection requires clicking "More choices" → "Use a different account" every time
  • Username not remembered despite saving in RDP file

Solution

Edit your .rdp file with these key settings:

full address:s:xetawsdev85.xemt.dev 
domain:s:XEMT 
username:s:David.Wei 
enablecredsspsupport:i:0

However， for another VM I have on another domain, I have to setup as the following to get it work

domain:s:LAKROS
username:s:[email protected]
enablecredsspsupport:i:1

Key Points

1. Separate domain and username - don't use XEMT\David.Wei format in RDP file
2. Set authentication level:i:2 - forces proper authentication (this step has been proved not necessory)
3. Disable CredSSP support - enablecredsspsupport:i:0 is essential (tested, this is the KEY option!) OR Enable CredSSP support (I don't know why, but some VMs do work with Disabled and some others work with Enabled, if one way doesn't work for you, try another. Also, the username format also matters, some VMs want a short name and some VMs need a full email address)
4. If you see a certificate warning on first connection - check "Don't ask me again"

Result

Username will be pre-filled correctly, only password entry required.

solution

Basically, you need to change or add the following options. The first three lines you can simply copy, but the fourth line, you should change to your own values.

screen mode id:i:2
use multimon:i:1
span monitors:i:1
selectedmonitors:s:3,4

explanation:

• screen mode id:i:2 -- i means integer: 2 means fullscreen mode

• use multimon:i:1 -- the remote desktop session will use multiple montiors

• span monitors:i:1 -- allow to use part of the monitors for remote desktop session

• selectedmonitors:s:3,4 -- specify what monitors you want to use: the value 3,4 could be different from yours. run mstsc /l (l here is L in lowercase) to check your own monitor ids.

Reference

Recently, I found it became very slow when I am logging onto my development VM, a windows server 2012R2 instance through Remote Desktop. There are many kinds of solutions in Google's search results. I tried many of them and found only this one suits me.

On the Windows Server 2012 machine, disable the Large Send Offload via the following steps:

Open Network Connections. 
Click Change adapter settings
Right-click the icon of the Network card and select Properties.
In Networking tab, click Configure… button.
In the next window, switch to Advanced tab.
Click the Large Send Offload Version 2 (IPv4) and change the value to Disabled.
Click the Large Send Offload Version 2 (IPv6) and change the value to Disabled.

Your RDP connection will disconnect right away after you apply the change. Don't worry, connect it back and you will find the annoying delay disappears!
