When I try to start the Central Administration, this appears:System.ArgumentNullException: No message was deserialized prior to calling the DispatchChannelSink. Parameter name: requestMsg at System.Runtime.Remoting.Channels.DispatchChannelSink.ProcessMessage(IServerChannelSinkStack sinkStack, IMessage requestMsg, ITransportHeaders requestHeaders, Stream requestStream, IMessage& responseMsg, ITransportHeaders& responseHeaders, Stream& responseStream) at System.Runtime.Remoting.Channels.SoapServerFormatterSink.ProcessMessage(IServerChannelSinkStack sinkStack, IMessage requestMsg, ITransportHeaders requestHeaders, Stream requestStream, IMessage& responseMsg, ITransportHeaders& responseHeaders, Stream& responseStream) at System.Runtime.Remoting.Channels.Http.HttpServerTransportSink.ServiceRequest(Object state) at System.Runtime.Remoting.Channels.SocketHandler.ProcessRequestNow() There is no Skype on the Server, or another Application that is using Port 80..So what to do to solve this?

Hi, Have you tried resetting the IIS or the application pool? What was the last action before facing the error?Best Regards, G Vijai Kumar My Sharepoint Blog

From where are you trying to open the central admin page. try opening it from IIS, Right Click on Sharepoint central Admin.. and say Browse.Are you able to access any other webapplications.Last option if any thing else doesn't worked is to re-run the configuration wizard. It will either fix the issue or else give the exact reasn why the error came. Regards, Aj (http://www.ajittgeorge.blogspot.com) MCTS

System.ArgumentNullException: No message was deserialized prior to calling the DispatchChannelSink. Parameter name: requestMsg at System.Runtime.Remoting .Channels.DispatchChannelSink.ProcessMessage(IServerChannelSinkStack sinkStack, IMessage requestMsg, ITransportHeaders requestHeaders, Stream requestStream, IMessage& responseMsg, ITransportHeaders& responseHeaders, Stream& responseStream) at System.Runtime.Remoting .Channels.SoapServerFormatterSink.ProcessMessage(IServerChannelSinkStack sinkStack, IMessage requestMsg, ITransportHeaders requestHeaders, Stream requestStream, IMessage& responseMsg, ITransportHeaders& responseHeaders, Stream& responseStream) at System.Runtime.Remoting .Channels.Http.HttpServerTransportSink.ServiceRequest(Object state) at System.Runtime.Remoting .Channels.SocketHandler.ProcessRequestNow() I guess the problem is with closing remote sessions, make sure whether you have closed the remote session properly or notBest Regards, G Vijai Kumar | My Sharepoint Blog

Solved: Wizard -> Disconnect from Farm -> Reconnect with another port

Hi. I had the same issue. Fix: Find a SharePoint process that is using the same port. netstat -na -nao>>find the Central Adm Port e and the Process IDs>>go to Task Manager and kill those process (in my case, the process was Microsoft.SharePoint...)...after this, iisreset. It worked for me!
