I have a desktop computer that is hooked up to our network here that is confusing me. The computer can get through the internet, transfer files over FTP, and do basic day to day tasks with reliable speed. However, when I try to ping local computers or try to remote in to a local server I time out or lose connection after a minute in. Is there something that I'm missing in my configuration of this desktop computer? I have setup other office computers, but this is the only one giving me issues. Any advice would be greatly appreciated.
