Many of you are aware that I modified the Client.msi and I created a Blogcast on how to do it. To save you the time of editing the Client.msi, you can now download it! The ModClient.MSI will set the SMSSITECODE=AUTO property and increase the cache to 1000 MB. Please make sure you test it before production use!! The MSI is running on thousands of computers without issue, but you should still test it to make sure you know it works for you.
This is the SMS 2003 SP1 Client.msi. You can use it just as you do the regular Client.msi. I renamed it so you know it's not the original file.
