限制一個帳號登入多台工作站

[psac]

首先,先建立兩個指令碼文件..分別為LOGON.VBS,LOGOFF.VBS.

LOGON.VBS

Option Explicit
Dim oNet, sUser, sComputer, ServerLog

ServerLog = "\\SERVERNAME\logctrl$\" 加$目的是為了用戶在遊覽伺服器共享文件的時候看不到.這樣用戶就無法來更改他們的登入信息..
Set oNet = CreateObject("Wscript.Network")
sUser = oNet.UserName
sComputer = oNet.ComputerName
Set oNet = Nothing

Dim fso, f1, WshShell, argu, alllog, lastlog
Dim FileName
FileName=ServerLog & sUser & ".txt"
Set fso = CreateObject("Scripting.FileSystemObject")
If Not (fso.FileExists(FileName)) Then
Set f1 = fso.CreateTextFile(FileName,True)
f1.WriteLine sUser & " " & sComputer
f1.Close
Set WshShell = Wscript.CreateObject("Wscript.Shell")
argu = FileName & "/T/E/G" & sUser & ":f /R Everyone"
WshShell.run("cacls " & argu)
Set WshShell = Nothing
End If

Set f1 = fso.OpenTextFile(FileName, 1, True)
alllog = f1.readall
f1.Close
Set f1 = fso.OpenTextFile(FileName, 1, True)
lastlog = f1.readline
f1.Close


If Left(lastlog, 5) = "logon" Then '判斷是否登入
If InStr(lastlog,sComputer) < 1 Then '判斷是否同一台機器，如果不是，往下執行
Set f1 = fso.OpenTextFile(FileName, 2, True)
f1.WriteLine (lastlog & Chr(13) & Chr(10) & "fail-so-logoff:" & Now() & " " & sUser & " at " & scomputer & Chr(13) & Chr(10) & alllog)
f1.Close

Set WshShell = Wscript.CreateObject("Wscript.Shell")
Dim i,OldComputer
i=InStr(lastlog,"at")
OldComputer=Right(lastlog,Len(lastlog)-i-2)
WshShell.popup "對不起:此帳號已經在 " & OldComputer & " 上登入使用！出現此提示,如是你還沒有登入，說明你的帳號被盜，請及時上報技術部，謝謝合作！！！" , 30
Set WshShell = Nothing
Dim os, retcode
For Each os In GetObject("Winmgmts:{impersonationLevel=impersonate,(shutdown,remoteshutdown)}!//" + sComputer).InstancesOf("Win32_OperatingSystem")
retcode = os.Win32ShutDown(4, 0)
Next
Wscript.quit
Else
Set f1 = fso.OpenTextFile(FileName, 2, True)
f1.WriteLine ("logon: " & Now() & " " & sUser & " at " & sComputer & Chr(13) & Chr(10) & alllog)
f1.Close
End If
Else '沒有登入
Set f1 = fso.OpenTextFile(FileName, 2, True)
f1.WriteLine ("logon: " & Now() & " " & sUser & " at " & sComputer & Chr(13) & Chr(10) & alllog)
f1.Close
End If
Set f1 = Nothing
Set fso = Nothing
Wscript.quit

LOGOFF.VBS

option explicit
dim oNet,sUser,sComputer,ServerLog
ServerLog = "\\SERVERNAME\logctrl$\"
set oNet=createobject("Wscript.Network")
sUser=oNet.UserName
sComputer=oNet.ComputerName
set oNet=nothing

dim fso,f1,alllog,lastlog
Dim FileName
FileName=ServerLog & sUser & ".txt"

set fso=createobject("Scripting.filesystemobject")
set f1=fso.opentextfile(FileName,1,true)
lastlog=f1.readline
f1.close
set f1=fso.opentextfile(FileName,1,true)
alllog=f1.readall
f1.close
if left(lastlog,5)="logon" Then
If InStr(lastlog,sComputer) > 0 Then '判斷是否同一台機器，如果是，往下執行
Set f1=fso.opentextfile(FileName,2,true)
f1.writeline("logoff: " & Now() & " " & suser & " at " & scomputer & Chr(13) & chr(10) & alllog)
f1.close
End If
end if
set f1=nothing
set fso=nothing
wscript.quit

我最初對蔣世濱先生寫那遍文章感興趣,試完之後覺得有存在一些問題,所以進行適當的修改.我在2000 ADVANCED SERVER測試通過.

如大家在測試程序中出現的問題,可以進行深入探討.
