Or logoff all users via command line

That works but it doesn't logoff disconnected sessions?

I have been through all this. Can someone please tell me the exact command that would work in a Windows Server 2008 environment to logoff /reset disconnected sessions via a command line :(
Didn't specify the command line option(s) for [username] end, sorry.

Easiest way I know is PsTools:
psshutdown -o

psshutdown -o doesn't logoff /reset disconnected sessions?
Ah no. No it doesn't. Hmm, yeah, just for active sessions.

The only sure way I can think of via command line is the session based...

net use /user:[username] \\servername\share
query session /server:servername
reset session [ID] /server:servername

Another interesting means to achieve your goals would be to alter the group policy settings via command line, setting a very short timeout on disconnected sessions. Definitely one that's easier to achieve via qpedit.msc, but doable via console.

|edit:| Here's the command:
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v MaxDisconnectionTime /t REG_DWORD /d "60000" /f

Thanks I knew those commands. I'm keen to know a way via command line not GPO
I'm just curious why you can only use <username>, or why you cannot use:

query user <username>
logoff [id] // where [id] is returned from query.

I simply want to logoff all disconnected sessions from a command line. :(
When you asked for it to be based off username, I thought you wanted it to be based off username for some reason... ie specific session termination; which I mentioned in previous comment - a command line means to disconnect a specific session querying their username to find session id.
Another command line kill of specific session:
get session:
   qwinsta /SERVER:servername
remove session:
   rwinsta {sessionname | sessionid} /SERVER:servername

Compliments of this.
Here's a script which will find all disconnected sessions and terminate them.
' logoff.vbs
' Finds all active TS sessions on server HOST defined
' below and terminates them.  Does not terminate the
' current session if being run remotely.
' If running on local host, set HOST value to ""

'// Added to Create and Open a file to write to
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objOutputFile = objFSO.CreateTextFile(".\ErrorLog.txt", True)

Host = ""
' Get disconnected sessions and log them off
sessions = DisconnectedSessions(Host) 
For each session in sessions 
    objOutputFile.WriteLine("sessionId = " & session) 
    TerminateWinSession Host, session


Sub TerminateWinSession(Host, sessionId)
    Dim Sh, tmpHost
    Set Sh = createobject("WScript.Shell")
    If trim(Host)="" Then
        tmpHost = ""
        tmpHost = " /SERVER:" & Host
    End If
    objOutputFile.WriteLine("Executing... " & vbCrLf & "%COMSPEC% /C rwinsta " & sessionId & tmpHost & vbCrLf)
    Sh.Run "%COMSPEC% /C rwinsta " & sessionId & tmpHost, 0, False
    If Err <> 0 Then
        objOutputFile.WriteLine("Error: " & Err.Number & " " & Err.Description)
    End If
End Sub

Function DisconnectedSessions(Host) 
    Dim tmpHost, aTmp, aTmp1(), i , DiscCount
    If Trim(Host)="" Then 
        tmpHost = "" 
        tmpHost = " /SERVER:" & Host 
    End If 
    objOutputFile.WriteLine("Executing... " & vbCrLf & "qwinsta" & tmpHost & " | find ""Disc""" & vbCrLf) 
    aTmp = Split(cmd("qwinsta" & tmpHost & " | find ""Disc"""),vbCrLf) 
    ReDim aTmp1(LBound(aTmp) to UBound(aTmp)) 
    DiscCount = 0
    For i = 0 to UBound(aTmp) 
        If Left(aTmp(i),1) <> ">" Then 
             aTmp1(DiscCount) = Val(Mid(aTmp(i), 42, 6)) 
             DiscCount = DiscCount + 1
        End If 
    Redim Preserve aTmp1(LBound(aTmp) To (DiscCount - 1)) 

    DisconnectedSessions = aTmp1 
End Function 

Function Cmd(cmdline)
' Wrapper for getting StdOut from a console command
    Dim Sh, FSO, fOut, OutF, sCmd
    Set Sh = createobject("WScript.Shell")
    fOut = objFSO.GetTempName
    sCmd = "%COMSPEC% /c " & cmdline & " >" & fOut
    objOutputFile.WriteLine("Executing... " & vbCrLf & sCmd & vbCrLf)
    Sh.Run sCmd, 0, True
    If Err <> 0 Then
        objOutputFile.WriteLine("Error: " & Err.Number & " " & Err.Description)
    End If
    If objFSO.FileExists(fOut) Then
        If objFSO.GetFile(fOut).Size>0 Then
            Set OutF = objFSO.OpenTextFile(fOut)
            Cmd = OutF.Readall
            objOutputFile.Write(Cmd & vbCrLf)
        End If
    End If

Have you try "net session"? You can do it from your desktop with "qwinsta" (Query) or "rwinsta" (Kill).

I don't think you can kill sessions based on username, regardless, you can see which username assoicated with the session anyway.

Hope this help.

In the end I wrote the following script for session id's 1-30.

logoff <session id> /server:<servername>

I knew this code anyway. It's not ideal but does the job :)

Thanks for everyone's input
