Hello. Thank you for coming to JustAnswer.
Sorry for the wait. My name is Michael. I will be helping you with your question today.
You should be able to access it on the network as long as you have the correct IP address. If you are getting a 404 error, that is most likely because of the IP address being incorrect. Is this your first time trying to access it?
Also, I would try using chrome browser just to rule out an issue with IE, which has security restrictions on local IPs.
