SaveIt is usefull to first grab a list of all of the computers in your domain. This vb script will do so (copy and past it into notepad and then save as getcomputers.vbs) ***********Script************* Const ADS_SCOPE_SUBTREE = 2 set fs = CreateObject("Scripting.FileSystemObject") set textstream = fs.CreateTextFile("hosts.xml", True) Set rootDSE = GetObject("LDAP://RootDSE") domainContainer = rootDSE.Get("defaultNamingContext") Set objConnection = CreateObject("ADODB.Connection") Set objCommand = CreateObject("ADODB.Command") objConnection.Provider = "ADsDSOObject" objConnection.Open "Active Directory Provider" Set objCOmmand.ActiveConnection = objConnection objCommand.CommandText = _ "Select Name, distinguishedName from 'LDAP://" & domainContainer & "' " _ & "Where objectClass='computer'" objCommand.Properties("Page Size") = 1000 objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE Set objRecordSet = objCommand.Execute objRecordSet.MoveFirst Do Until objRecordSet.EOF 'Wscript.Echo "Computer Name: " & objRecordSet.Fields("Name").Value 'Wscript.Echo "distinguishedName: " & objRecordSet.Fields("distinguishedName").Value arrPath = Split(objRecordSet.Fields("distinguishedName").Value, ",") strOU = "" for each a in arrPath if left(a,2) = "OU" Then strOU = "/" & right(a,len(a) - 3) & strOU End If Next 'Wscript.Echo "Path: " & StrOU textstream.WriteLine objRecordSet.Fields("Name").Value objRecordSet.MoveNext Loop textstream.close Wscript.Echo "Finished..." ************End Script*************** Ok, so that will save a file called hosts.xml. Edit it to remove any computer names that you don't want to install WPKG on. Copy this file to your root c:\ Download PStools. http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx To make it easy, install it to the root of your c:\ drive. Download the WPKG clientt http://www1.wpkg.org/files/client/stable/WPKG%20Client%201.2.1.msi and copy it over to a remote share. Also, copy over your settings file to the same remote share. When you are ready to install, execute this psexec command: (Replacing yourdomain, adminuser, yourpassword, and yourserver with your values) c:\psexec -y yourdomain\adminuser -p yourpassword @hosts.xml -s -d msiexec /i "\\yourserver\wpkg\WPKG Client 1.2.1.msi" /qb SETTINGSFILE=\\yourserver\wpkg\settings.xml This will then install WPKG on any of these clients that happen to be on at the time :)
