The following instructions are generic Remote Desktop instructions for basic remote access to a Bren Terminal Server. If you need access to a Bren GIS lab computer for a remotely taught class use these instruction instead: Remotely controlling GIS / lab computers from your home Mac or PC using availability lists
To connect to any computer on the Bren Network from outside UCSB, you must use the Campus VPN first. Instructions for that are HERE. The rest of this help page covers installing/using remote desktop which you probably already know.
Computers with Windows 10 should already have the software you need to connect to the Bren Terminal Servers pre-installed however if you are running Mac/OSX please you can download Microsoft Remote Desktop from the Apple App Store.
Existing Mac Remote Desktop user having trouble connecting?
Recently there have been reports of users seeing an error message and not being able to connect when previously they could. First verify that the VPN is working correctly, if the problem persists, remove the Remote Desktop Application and reinstall it. This process appears to fix the issue users are having.
On most Windows computers you can find the Remote Desktop Icon here:
Start -> Programs -> Accessories -> Communications -> 'Remote Desktop Connection'
Once you click on it, you will see the following:
If this is the first time you have used Remote Desktop Connection you will probably want to check through the settings, to do this click the Options button, then click on the General tab.
Computer: You will want to enter either 'snoopy.bren.ucsb.edu' or 'woodstock.bren.ucsb.edu'
User Name: use ESM\username where username is your Bren Windows account username.
Password: The password for the above account
Under the "Display" tab change the size of the remote desktop session to the desired size, typically this would be all the way to the right or Full Screen.
If you have a slower/intermittent internet connection the following options may improve performance:
Under the "Local Resources" tab unselect "Printers" and "Clipboard" from the Local devices and resources section.
Under the same tab click on the "Settings" button and select "Do not play" and "Do not record" radial button options. 
Then click 'Connect', you should now be logged into the Bren Terminal Servers you specified.
