I am looking right now at the live log as the WSUS server tries to go out and download files. When I highlight one of the Failed Connection Attempts, in the upper pane the URL is listed as http://70.37.129.29/msdownload/update/software/defu/2010/04/mpam-fe_128bde14f8e8f74f6fa189cfdf28eff7829a3ed8.exe In the lower pane, the Destination is listed as "External (cds24.ewr9.msecn.net 70.37.129.29:80)".

The WSUS team insists that WSUS will not make requests this way.

I got tied up with other things, and since my creation of the Source Exception for WSUS made it work, this slipped in priority. Today I deleted the Source Exception and tried again to download files with WSUS. Again that failed. The thing is, WSUS doesn't appear to be trying to pull files from any of those built-in Destination Exceptions you mentioned (*.microsoft.com, *.windows.com and *.windowsupdate.com). According to the log, it's trying to pull files from "cds118.ewr9.msecn.net 70.37.129.123:80". So it doesn't seem like those Destination Exceptions would help.

Use NetMon at the TMG and set the log viewer to monitor traffic from the WSUS server. Are you sure the WSUS proxy settings are right?

If this isn't your experience, someone has been playing silly buggers in your deployment.

At least that was my experience today. Thanks, Rob -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rob Moore Network Manager 215-241-7870 Helpdesk: 800-500-AFSC
