There is no information to provide any clue as to whether the PC or the server is at fault. I would suggest packet capture. On a Windows system, I suggest wireshark. The same for the server, if it is yours. If the server is Unix and you have access to do so, just simple tcpdump will work well. -- R. Kevin Oberman, Network Engineer E-mail: rkober...@gmail.com
