I have one computer (our newest XP Pro SP2 desktop) that is having some network problems. We have a program that runs one master and the rest of the desktops connect TCP/IP. This one desktop keeps losing connection to the master program. The other system that desktop has trouble with is we have a new streaming video on our website. This desktop is the only one that has lag. We are connected to a new 2003 windows server. Is there a setting I should look at?
