I am trying to automate/script the process of adding a Win7 SP1 computer to AD. We are running with both domain and forest functional levels at 2008 R2. This code works to put the object in the Computer container: ConstJOIN_DOMAIN=1 ConstACCT_CREATE=2 ConstFORCE_JOIN=32 DimoShell, sUser,sPassword,sDomain,oWMI,oCmp,sReturn sUser="TestUser" sPassword="password" sDomain="mydomain" SetoWMI=GetObject("winmgmts:\\.\root\cimv2") ForEachoCmpinoWMI.InstancesOf("Win32_ComputerSystem") sReturn=oCmp.JoinDomainOrWorkgroup(sDomain,sPassword,sDomain&"\"&sUser,Null,JOIN_DOMAIN+ACCT_CREATE+FORCE_JOIN) IfsReturn<>0Then WScript.Echo"Joindomainfailed.Error="&Err.Number&vbCrLf&"Exitingscript." Else WScript.Echo"Joindomainsuccessful." EndIf Next But if I specify the OU to put the object in like: sOU = "OU=laptops,OU=ejws,DC=mydomain,DC=com" oCmp.JoinDomainOrWorkgroup(sDomain,sPassword,sDomain&"\"&sUser,sOU,JOIN_DOMAIN+ACCT_CREATE+FORCE_JOIN) C:\Windows\debug\Net says "Cannot retry downlevel, specifying OU is not supported" I've found some info on the net about a bug when using a domain/forest functional level of Win 2000, but nothing for 2008 R2.

I would have ask here. http://social.technet.microsoft.com/Forums/en-US/ITCG/threads Thanks

Figured it out, you have to use ";" instead of "," like this: sOU = "OU=laptops;OU=ejws;DC=mydomain;DC=com"

The use of semicolons is described in the notes to this article describing the JoinDomainOrWorkgroup method: http://msdn.microsoft.com/en-us/library/windows/desktop/aa392154(v=vs.85).aspx Richard Mueller - MVP Directory Services
