Windows Script Host
Script:   D:\libarary\Desktop\ComputerDescrition.vbs
Line:     9
Char:    1
Code:    80070005
Source:  Active Directory

Script:
Set objSysInfo = CreateObject("ADSystemInfo")

Set objUser = GetObject("LDAP://" & objSysInfo.UserName)
Set objComputer = GetObject("LDAP://" & objSysInfo.ComputerName)

strMessage = objUser.CN & " logged on to " & objComputer.CN & " " & Now & "."

objComputer.SetInfo

It is run success when i log on a computer use Domain Admin,I guess it is  a Domain Permission issue,but how do I give my domain users permission to change the description attribute for their computer?

Answer : Computer Description Permission of Domain user

Set up the rights as explained by oBdA:
But I also did the same for the Computer objects, you have to do the rights for the Computer description.
The following script skips the update if the OS is a server OS.  This way citrix server logon etc don't change server descriptions.  Also you can look up users by computer name and also coputers via user name.  I place the full contect of the user name in the description.  You can modify it not give the full contect.

' ********************************************************************
' This script Modifies a User Desscription field and Computer Description
' field in AD with User Name, Computer Name, and Login Date & Time,
' and User Context
' Skips if the computer is running a server version of Windows
' ********************************************************************

on error resume next

Set objSysInfo = CreateObject("ADSystemInfo")
Set objComputer = GetObject("LDAP://" & objSysInfo.ComputerName)
Set objUser = GetObject("LDAP://" & objSysInfo.UserName)

strOS = objComputer.operatingSystem

    If InStr(UCase(strOS),"SERVER")  Then

       
    Else

       strmessage1 = objComputer.CN & ", " & Now &", " & objSysInfo.UserName
       strMessage2 = objUser.CN & ", " & objComputer.CN & ", " & Now & ", " & objSysInfo.UserName

       objUser.Description = strMessage1
       objUser.SetInfo

       objComputer.Description = strMessage2
       objComputer.SetInfo

    End If
