c# remoting - spin off customerrors

i removing following blunder i try bond server app controlling remoting:

a problem seems have occured while joining remote server:

server encountered an middle error. some-more information, spin off customerrors server's .config file.

this formula server app:

tcpchannel tcpchannel = new tcpchannel(999);
myremoteobject remobj = new myremoteobject (this);
remotingservices.marshal(remobj, "myuri");
channelservices.registerchannel(tcpchannel);

it seems work initial time, nonetheless unless server app restarted blunder occurs.

i speculation something isn't being spotless adult morally nonetheless i'm certain customerror still on.

any ideas where i start. thanks.

remotingconfiguration.customerrorsmode = customerrorsmodes.off;
tcpchannel tcpchannel = new tcpchannel(999);
myremoteobject remobj = new myremoteobject (this);
remotingservices.marshal(remobj, "myuri");
