I've got a HP MediaSmart Windows Home Server EX490 and I'd like to run my own Minecraft server.

I have the server software downloaded on my WHS box, so through a Remote Desktop connecting I startup the software which runs fine.

However the moment a Minecraft client trys to connect to the server, my Remote Desktop connection freezes and the whole WHS appears to be frozen.

I've tried this a number of the times and get the same result each time. Is there a reason why WHS would do this? Has anyone else had the same issue?

    this may be unrelated, but minecraft.net's auth has been having some serious problems. I can only connect to my server if I put 'online-mode=false' in server.properties to bypass the auth entirely.

  • @cory-j Just given the 'online-mode=false' a go, but the problem is still there :( @badp Yup, still have the problem. Been hosting the server on a spare computer at my parent's house, if you can believe it! Commented Feb 27, 2011 at 19:30

    From the log, your server is overloaded just serving one player connection. What are the specs on this machine? Commented Jun 23, 2011 at 1:22

I haven't touched it recently, but I was running Minecraft fine on my WHS (an HP LX190) without any real problems. I followed these directions to run it as a service so I didn't have to leave an RDP session going:


Install Summary - Download yajsw and extract to any folder. - Open task manager and find the "java" pid under processes. This is most likely your minecraft server. - Open a command prompt and browse to the "bat" folder under yajsw. (ex. D:\yajsw-beta-10.3\bat). - Run genConfig.bat (ex. genConfig.bat 2467).

wrapper.conf - Browse to "conf" folder (ex. D:\yajsw-beta-10.3\conf) and open wrapper.conf in a text editor. - Set the working directory to your minecraft .jar server file. (ex. \minecraftserver\ for D:\minecraftserver). - Uncomment wrapper.app.password and enter your admin account password. Make sure the username on the line above is correct. - Fill in service name and descriptions.

Create/Install Service - Run installService.bat from the bat directory. (ex. D:\yajsw-beta-10.3\bat) - Open Services Manager through administration tools. - Right click the server, properties. - Browse to "Log On" tab. - Change to "This Account" and use the same account in your wrapper.conf.

Start the service.

Minecraft runs on port 25565, so it shouldn't be conflicting with RDP anyway (which is 3389), but this makes things much easier for me anyway.


Check to see if Minecraft is running on the same port as remote desktop. This could cause a port conflict that might freeze your system.
