Hopefully, these steps will help you connect your MacBook to your corporate server.
First, download the app: https://itunes.apple.com/en/app/microsoft-remote-desktop/id715768417?mt=12. To download Microsoft Remote Desktop from the Mac App Store, you need a Mac with OS X 10.6.6 or later.
After you have installed it, start the app.
Click “New”
In the “Connection name”, enter a friendly name to help identify the connection
In the “PC name” field, enter the name/IP address of the PC/server you want to connect to
Under “Credentials”, in the “User name” field, enter “domainusername” (without quotes)
In the “Password”, enter your password
In the “Gateway” dropdown, select “Add gateway”
In the “Gateway name”, enter a friendly name to identify the Gateway.
In the “Server” field, enter the fully qualified domain name or public IP address of the Gateway server
In the “User name” field, enter the credentials given to you by your administrator.
In the “Password” field, enter the password for the user name above.
In some instances, it may be possible that your credentials will be enough to connect through the Gateway, in which case, you may not need to enter the credentials here.
Click the close (red) button on the top left to save the settings,
Now select the gateway you just added above as the Gateway for the connection you were creating.
After the Gateway has been selected, you can click the close (red) button on the top left to save the settings for this connection.
If all the settings have been entered correctly, you should now be able to connect to your corporate server.
Thank Sri 🙂
