Problem with clients getting updates from SUS Server

I have built a SUS server for patching my network, after downloading updates to it I created a vbScript to auto configure each client. Haveing the clients configured they are now not getting updates from the SUS server. The client update log located C:/Windows/Windows Update.log Reads that has “Success IUCTL starting” then “Downloaded iuident.cab from http://xxx.xxx.xxx.xxx/ to C:\Program Files\WindowsUpdate\V4” followed with “starting” then repeats “Determining machine configuration Querying software update catalog from http://xxx.xxx.xxx.xxx/autoupdate/getmanifest.asp” several times and reads Shutting down. Nothing is updated, is there any thing that may have been missed or mal-configured? Please Help!
