WSUS Event 364: 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.


My WSUS server, which became a WSUS client yesterday, reported the following error this morning:

Event 364  Source: Windows Server Update  Category:  Synchronization

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/v3-19990518/cabpool/visio2002-kb917150-fullfile-glb_c086ab10bda5e695d8ea26d91a690e225fc239d6.cab Destination File: d:\WSUS\WsusContent\D6\C086AB10BDA5E695D8EA26D91A690E225FC239D6.CAB.

KB 922330 says the problem is because the affected computer is behind a firewall or proxy.  They specifically mention Sonicwall security appliances as a culprit and suggest selecting the Enable HTTP Byte-Range request with Gateway AV check box on the Sonicwall configuration. This particular WSUS client does sit behind a Sonicwall 3060 security appliance.  I went into the Sonicwall administation page, but could not find where to enable this feature.  Luckily I came across this post, where J.B. pointed out where to find the setting:  

“Instructions for Sonic Enhanced OS:
Click Security Services, Gateway Anti-Virus, Configure Gateway AV Settings.
Check the box for “Enable HTTP Byte-Range requests with Gateway AV”. 

I made the change to the Sonicwall, then ran wuauclt /detectnow on the WSUS server/client.  We’ll see if the Event 364 reappears.
