For some reason WSUS stopped downloading updates! On the Default WSUS program page, it gives me the following info:

Synchronization Status
Status: idle
Last Synch: 10/20/2008 1:18pm (because I just tried to synch again)
Last Synch Results: Succeeded

Download Status
Updates Needing Files: 217
Downloaded 0.00 MB of 4,791.51 MB

Connection
Type: Local/SSL
Port: 80
User Role: Administrator
Server Version: 3.0.6000.374

And the event viewer shows me this error for all the downloads that did not work:

Content file download failed. Reason: The server does not support the necessary HTTP protocol. Background Intelligent Transfer Service (BITS) requires that the server support the Range protocol header.
 Source File: /msdownload/update/software/secu/2008/09/windowsserver2003.windowsxp-kb956841-x64-enu_95303a91198a9ba1467e5bd23be11bb97e31b1e7.exe Destination File: c:\WSUS\WsusContent\E7\95303A91198A9BA1467E5BD23BE11BB97E31B1E7.exe.

I tried the URL directly and can dowload the updates and it works just fine so I don't think it's a firewall issue. I also have been directed to this site repeately by other posts: http://wsus.editme.com/ContentFileDownloadFailedAccessDeniedNoHTTP

but I do not have this tool in this directory: \osql\osql.exe

I have a Barracuda web filter, but I don't see it blocking anything from the server.

Anybody have any ideas?

This link is the same exact info that I posted in my question whick I already said did not help:

http://www.wsuswiki.com/ContentFileDownloadFailedAccessDeniedNoHTTP

The next link was a post that had nothing to do with what I was asking, but I did what was on that post anyway.I changed the login account type on Update Services from NT AUTHORITY\NetworkService to local service and restarted the service to no avail.

Any other ideas?

I have had this exact same issue.  Your problem is the Barracuda.  According to Barracuda, the range protocol header is not able to be exempted in the current firmware release.  I submitted a development request for this to be addressed in future firmware releases.  In the meantime, the two work-arounds available are:

a. exempt the WSUS server from all filtering on the Barracuda.

-or-

b. exempt the url's for the windows update sites in the Barracuda.  

I personally went with option a., since no one should be surfing on that pc anyway, and it has other means of spyware protection.

You Rock, thank you so much. I thought that might have been the issue, but couldn't figure out how to get it working!
