Problem
I have a number of servers on which I do screen experiments. The following is the procedure:
I can simply discover which servers the experiments are running on by sshing to all servers and listing my ongoing processes (using top or ps).
However, once the trials are complete, how can I determine which servers have a screen session open (so that I can inspect the output, relaunch them, and so on)?
PS: My tests also save their results to files, but that isn’t the purpose of my inquiry.

Run the following command as that user to see a list of all screen sessions:
screen -ls
You can do the following to observe all screen sessions on a specific machine:
ls -laR /var/run/screen/
This is what I get on my computer:
gentle ~ # ls -laR /var/run/screen/
/var/run/screen/:
total 1
drwxrwxr-x 4 root utmp 96 Mar 1 2005 .
drwxr-xr-x 10 root root 840 Feb 1 03:10 ..
drwx------ 2 josh users 88 Jan 13 11:33 S-josh
drwx------ 2 root root 48 Feb 11 10:50 S-root
/var/run/screen/S-josh:

To manage security, state, and streams, this is a fantastically Unixy usage of Unix Sockets wrapped in filesystem permissions.

It’s possible that the command screen -list is what you’re looking for.
See the man

Solution #3
While joshperry’s answer is correct, I find very annoying that it does not tell you the screen name (the one you set with -t option), that is actually what you use to identify a session. (not his fault, of course, that’s a screen’s flaw)
That’s why I prefer to use a script like this: grep -i screen|grep -v grep ps auxw

I’m not sure what you’re asking, but if all you want is a list of currently open screen sessions, try:
screen -ls

Solution #5
For windows system
Open putty
then login in server
If you wish to see the screen in the console, type command.
Screen -ls
If you need to access the screen, type the following command.
screen -x screen id
PWD is a command that will tell you the folder you are currently in.
