Thanks very much. You were right, simply modifying the lockingModel attribute was enough! Both my domains are now logging to the same file, which is exactly what I wanted!

I dont think its possible to share loggers or appenders across
AppDomains, log4net stores them in static structures. It they were
shared they would have to be marshal by ref objects, and then one of the
domains would log a lot slower than the other (as it would have to cross
the domain boundry for each call).

I've got different domains using the same config file by defining
loggers at the top of the namespace in each domain, and having them use
different appenders. So if domain 1 only uses classes from
Namespace1(and its descendants) , and domain2 only uses Namespace2

<logger name="Namespace1">
        <appender-ref ref="MyAppender1" />
<logger name="Namespace2">
        <appender-ref ref="MyAppender2/>

to have the different appenders in each domain write to the same file,
try setting the lockingModel of the RollingFile appender to MinimalLock.
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />

you will probably get by just changing the locking model and not doing
the first step.
