Quick Tip: proxy settings

Published on Thursday, February 23, 2012 in

I had a colleague which was configuring Symantec Mobile Device Management. The event log was showing messages of a service trying to connect to an URL but failing with 407 proxy authentication required. As far as we knew no proxy settings were configured. Well they were at a point, but not now…

Here’s what led me to the solution: http://www.symantec.com/business/support/index?page=content&id=TECH127695

Delete these keys:

  • HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\DefaultConnectionSettings
  • HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections\SavedLegacySettings

[Update] that same day I came across an identical issue but in SCCM with the Active Update Point configuration push towards WSUS.

From the WCM.log:
