Slow OSD download fixed (HTTP/WEBDAV issue)

This week I’ve been beating on a problem with an OSD Task Sequence. It is a TS for deploying the Vista image that I build with my Build and Capture TS. What I was noticing was that in my Deploy TS, it was simply taking entirely too long to download the WIM file. Now granted it is a 3.5gig file, but it was taking approximately 15 minutes to download. With the gigabit connection, it should have been about a minute and a half. WHY???

I enabled command support on my boot image, ran the TS, and pulled up an F8 CMD prompt to take a look at the smsts.log. It has some errors where the HTTP transport was failing with a 405 code. After failing three times, it then switched to SMB and proceeded to download…very slowly. Here is what I saw in the log:

Retrying download…

Tried all the available http based locations. SMB based locations will be attempted now.
