Hi, I would appreciate it if someone could help me analyze a capture file that I saved with WireShark. Lately, our throughput has dropped from our backup server. We have a separate network team that manages Cisco switches and routers. They claim that utilization is low on the switches, but they see packets being dropped or lost. They claim it's the server. I have done everything possible on this backup server which is running a HP DL380 hardware. I have upgraded firmware, drivers, NICs, etc. I have installed wireshark and used the Expert Info feature. The Expert Info feature shows that I have been getting a lot of bad tcp checksums, TCP duplicate ACKs, TCP previous segment lost, TCP out of order, and TCP fast retransmission. I have no experience with WireShark and unfortunately our network team can't interpret the capture file. Can somone please assist and provide advice as to what may be the cause of the problem and the reason in dropped throughput. Thanks in advance for any advice that can be provided.
