If you enable debugging inside of log4net: 

 <appSettings>
  <add key="log4net.Internal.Debug" value="true" />
 </appSettings>

and use ConfigureAndWatch to configure log4net, you should see a
message similiar to this when you make a change to your log4net.config
file. The text below was generated when I changed the level of my root
logger from ALL to OFF:

log4net: ConfigureAndWatchHandler: Changed
[c:\inetpub\wwwroot\log4net.config]
log4net: ConfigureAndWatchHandler: Changed
[c:\inetpub\wwwroot\log4net.config]
log4net: XmlConfigurator: configuring repository
[log4net-default-repository] using file
[c:/inetpub/wwwroot/log4net.config]
log4net: XmlConfigurator: configuring repository
[log4net-default-repository] using stream
log4net: XmlConfigurator: loading XML configuration
log4net: XmlConfigurator: Configuring Repository
[log4net-default-repository]
log4net: XmlHierarchyConfigurator: Configuration update mode [Merge].
log4net: XmlHierarchyConfigurator: Logger [root] Level string is [OFF].
log4net: XmlHierarchyConfigurator: Logger [root] level set to
[name="OFF",value=2147483647].
...

It looks like you're configuring log4net twice. A better approach may
be to use your own AdoNetAppender: 

public class MyAdoNetAppender : AdoNetAppender
{
 protected string ConnectionString 
 {
  get { return base.ConnectionString; }
  set { base.ConnectionString =
ConfigurationSettings.AppSettings["Logger.ConnectionString"]; }
 }
}

Your call to configure log4net will look something like this:

 FileInfo log4netConfig = GetLog4netConfigFile();
 log4net.Config.DOMConfigurator.ConfigureAndWatch(log4netConfig);
