wsus 3.0: Bandwidth throttle did not work?

[news.microsoft.com]

Hi,

We upgraded wsus from version 2 to 3 about two months ago.

A month ago we replaced our ISA server but I never updated wsus proxy
settings to point to new server.

Yesterday I saw wsus hadn't synchronised for a month so I changed the
settings to point to new ISA server.

I set the synchronisation going around 3pm, but after half an hour it
brought our internet and vpn traffic to standstill as it hogged all the
available bandwidth (around 1.5mbps) while it downloaded over a gigabyte of
updates.

I thought it was meant to be throttled so I just checked the BITS settings
in group policy and resultant set of policy on machine - it says to limit
the bits transfer rate to 7kbps between 8am and 8pm, and at all other times
to use all available bandwidth.

Does anyone have any idea why this setting may no longer work? (I'm fairly
sure it use to behave under version 2 of wsus).

Or what I can do to make it work properly again?

Regards,

Bryce Stenberg.

First thing I'd do is make sure some "other administrator" hasn't put WSUS
into "Foreground Mode", which essentially bypasses the BITS throttling.

The WSUS Server Debug Utility can be used to toggle WSUS/BITS in and out of
Foreground mode.

Hi Lawrence,

When I ran 'WsusDebugTool.exe /Tool:GetConfiguration'
it showed 'BitsDownloadPriorityForeground' was set to 'true'.

I ran it with the ResetForegroundDownload and now the
'BitsDownloadPriorityForeground' is set to 'false'.

So now all should be good. Thanks muchly for your assistance.

Regards,
Bryce.
