a few users have logged into a server through RDP.
I would like to monitor activity, but do not know my way round Windows Server that well.
I am hoping there are logs of some kind around that I can consult.
Any ideas? :)

A few options..
eventvwr.msc
)Applications and Services Logs
-> Microsoft
-> Windows
-> TerminalServices-LocalSessionManager
Admin
or Operational
You will see the sessions list. Date/Timestamped/IP/UserName etc. You can also look under Applications and Services Logs\Microsoft\Windows\TerminalServices-RemoteConnectionManager
Here's a solution in PowerShell:
Get-EventLog -LogName Security | ?{(4624,4778) -contains $_.EventID} | %{
(new-object -Type PSObject -Property @{
TimeGenerated = $_.TimeGenerated
ClientIP = $_.Message -replace '(?smi).*Source Network Address:\s+([^\s]+)\s+.*','$1'
UserName = $_.Message -replace '(?smi).*Account Name:\s+([^\s]+)\s+.*','$1'
UserDomain = $_.Message -replace '(?smi).*Account Domain:\s+([^\s]+)\s+.*','$1'
LogonType = $_.Message -replace '(?smi).*Logon Type:\s+([^\s]+)\s+.*','$1'
})
} | sort TimeGenerated -Descending | Select TimeGenerated, ClientIP `
, @{N='Username';E={'{0}\{1}' -f $_.UserDomain,$_.UserName}} `
, @{N='LogType';E={
switch ($_.LogonType) {
2 {'Interactive (logon at keyboard and screen of system)'}
3 {'Network (i.e. connection to shared folder)'}
4 {'Batch (i.e. scheduled task)'}
5 {'Service (i.e. service start)'}
7 {'Unlock (i.e. post screensaver)'}
8 {'NetworkCleartext (i.e. IIS)'}
9 {'NewCredentials (i.e. local impersonation process under existing connection)'}
10 {'RemoteInteractive (i.e. RDP)'}
11 {'CachedInteractive (i.e. interactive, but without network connection to validate against AD)'}
default {"LogType Not Recognised: $($_.LogonType)"}
}
}}
Information on the related EventIds we're filtering on can be found here:
For RDP connections you're specifically interested in LogType 10; RemoteInteractive; here I've not filtered in case the other types are of use; but it's trivial to add another filter if required.
You'll also need to ensure these logs are created; to do that:
Start
Control Panel
Administrative Tools
Local Security Policy
Security Settings
> Advanced Audit Policy Configuration
> System Audit Policies - Local Group Policy Object
> Logon/Logoff
Audit Logon
to Success
Other than combing through the event logs, looking for Logon Type 10 (Remote Desktop) in the Security Log, or looking at the TerminalServices channel event logs, you'll need to use third party software.
In addition to TSL mentioned above, here is one other I've used with success in the past - Remote Desktop Reporter
http://www.rdpsoft.com/products
If you go third party, make sure you evaluate several and get price quotes from each vendor ... there is a huge discrepancy in price - some vendors price per named user, some per concurrent user, and some simply by server. Make sure also that the solution comes with its own database or a lite version of SQL - otherwise you'll get hit with database license costs as well.
You can set any user account in AD for remote control to view or interact with a user's session by going to the Users tab in Task Manager, right clicking and select 'Remote Control'. You can then view their session.
I've been through most of the free/affordable answers on this page as well as searching elsewhere (for days, including reading the Event logs mentioned by Andy Bichler) and here's an alternate free RDP monitoring and blocking tool:
http://www.tweaking.com/content/page/remote_desktop_ip_monitor_blocker.html
I haven't tested it extensively, but downloaded and scanned it (the portable version) and although the UI is a bit on the ugly side, it's working on a 2012 R2 server without issue thus far. It's "hands on," but a no-brainer as well and beats deciphering the event logs.
There is also ts_block which allows you to automatically block IPs that are brute forcing your server's RDP (which I'm guessing would have some log of RDP attempts):
https://github.com/EvanAnderson/ts_block
As you can see in that link, the author is a serverfault user. I have not tested it as it's basically a vbscript that I would need to dissect before using. But, it seems promising.
The problem with the event logs mentioned by Andy above is that they are not very clear or descriptive as to who's doing what... at least in a malicious sense. You can find IP Addresses, but then it's hard to tell if they are related to all the unsuccessful login attempts. So, another tool other than the inherent logs seems almost mandatory if you're server is internet facing and you have any concerns about security.
in the eventlog -
Applications and Services Logs\Microsoft\Windows\remote desktop services-rdpcorets
there is all attempts to connect to rdp and the ip address
When I was working as an administrator few years back I had issue like you do now, I wanted to monitor everybody that connect via the RDP and exactly when and if they were active or idle.
I have evaluated few products but decided none of them is good enough for me so I built my own (the problem was every had some kind of an agent or service to collect the data, and the solution I built is using TS API to remotely to remote server and extract the data without any agent). The product is called now syskit (or TSL as Jim mentioned) and it is used widely all over the world :D
You can check user activities here
Run this in Powershell:
Get-WinEvent -ProviderName OpenSSH | Export-Csv -Path 'C:\Users\Windows10\Desktop\SSHLogs.csv' -NoTypeInformation
Your SSH logs file in CSV is ready!
