RemotingAppender error when called through a VB6 wrapper?

[Sam Smoot <ss...@gmail.com>]

We've made a wrapper so we can use log4net in some older VB6 apps like so:

[Guid("8949D706-9D81-4e24-A0DF-FC42E50AEFD9")]
	[ComVisible(true)]
	[ClassInterface(ClassInterfaceType.AutoDispatch)]
	public class Logger {
		public Logger() {}

		public void Configure(string xmlConfigurationFilePath) {
			RemotingConfiguration.Configure(xmlConfigurationFilePath);
			XmlConfigurator.ConfigureAndWatch(new FileInfo(xmlConfigurationFilePath));
		}
	
		public void SetLogger(string loggerName) {
			log = LogManager.GetLogger(loggerName);
		}

		ILog log;

		public void LogDebug(string message) {
			log.Debug(message);
		}

		public void LogInfo(string message) {
			log.Info(message);
		}

		public void LogWarn(string message) {
			log.Warn(message);
		}

		public void LogError(string message) {
			log.Error(message);
		}

		public void LogFatal(string message) {
			log.Fatal(message);
		}
	}

A FileAppender works fine, but we're getting exceptions in the
RemotingAppender setup in the configuration file. Such as the
following:

[4128] log4net:ERROR [RemotingAppender] Failed in SendBufferCallback 
[4128] System.Runtime.Remoting.RemotingException: Server encountered
an internal error.  For more information, turn on customErrors in the
server's .config file.

Trying to log to our centralized log server; or the following when
trying a local instance of the log server (we tried setting the
TypeLevelFilters to Full, but no dice):

[7812] log4net:ERROR [RemotingAppender] Failed in SendBufferCallback

Any ideas?
