Deleting Proxy settings from LiveUpdate configuration[Unmanaged Clients].
Some days ago I faced with an issue.
In a big network all Live Update applications were configured with Proxy[Unmanaged clients]. But the proxy setting were needed to be disabled.
Network configuration is handled by files:
which are situated in C:\Documents and Settings\All Users\Application Data\Symantec\LiveUpdate folder.
I think It could be useful.
