You could also use the TranslateName UDF as it will help cut down on syntax errors when needing the ldap path. You could do something like...

Code:
$group = "Domain Admins"  ; The group you are trying to connect to
$ldapgroup = TranslateName (3,"",3,@Domain+"\"+$group,1)[0]  ; Gets the LDAP path to the group

$adsGroup = GetObject("LDAP://"+$ldapgroup)  ; Connects to the ldap path of the group

If @Error <> 0
   $null = messagebox(@SError,@Error,0)
Else
   $null=messagebox($adsGroup.name,"Success",0)
Endif

Function TranslateName ($InitType, $BindName, $LookupNameType, $LookupName, $ReturnNameType)
   Dim $InitType, $BindName, $LookupNameType, $LookupName, $ReturnNameType
   Dim $NameTranslate, $ReturnName, $Error, $ErrorText
   $Error = 0
   $ErrorText = ""
   $ReturnName = ""
   $NameTranslate = CREATEOBJECT ("NameTranslate")
   $Error = @error
   $ErrorText = @serror
   if $Error = 0
      $NameTranslate.Init ($InitType, $BindName)
      $Error = @error
      $ErrorText = @serror
      if $Error = 0
         $NameTranslate.Set ($LookupNameType, $LookupName)
         $Error = @error
         $ErrorText = @serror
         if $Error = 0
            $ReturnName = $NameTranslate.Get($ReturnNameType)
            $Error = @error
            $ErrorText = @serror
         endif
      endif
   endif
   $TranslateName = $ReturnName, $Error, $ErrorText
