Error 00000071 could not find source for updated packages

Hello 

I'm having a bit of a problem with updates on the server that hosts my management console.

Looking around the KBs there is a possibilty of an error in th e config file iconn.cfg. At first glance everything looks ok, but we connect to the interenet using a web proxy service.

The config file looks like....

;****************************************************************************

; iconn.cfg
;
; Please do not edit this text file.

;****************************************************************************

[PPI.WebConfig_Primary]
AllowLocalConfig = 0
AutoDialTimeout =
LocalPath =
DownloadGranularity =
ConnectionAddress = \\local server name\SophosUpdate\CIDs\S000\SAVSCFXP\
UserName = Local server name\SophosUpdateMgr
UserPassword = Password is correct
ConnectionType = UNC
UseSophos = 0
AutoDial = 0
BandwidthLimit = 0
PortNumber =

[PPI.ProxyConfig_Primary]
AllowLocalConfig = 0
ProxyPortNumber = 0
ProxyType = 0

[PPI.WebConfig_Secondary]
AllowLocalConfig = 0
AutoDialTimeout =
LocalPath =
DownloadGranularity =
ConnectionAddress = http://es-web.sophos.com/update/
UseSophos = 1
UserName = Username is correct
UserPassword = Password is correct
ConnectionType = HTTP
AutoDial = 0
BandwidthLimit = 0

[PPI.ProxyConfig_Secondary]
AllowLocalConfig = 0
ProxyPortNumber = 0
ProxyType = 0

Is the problem down to the proxy details not being listed?

Thank you for your help
