We are running an internal Fog server with address 10.X.X.X and when we try logging into it between the hours of 8am-4pm, we are seeing sluggish response times. Ran wireshark and saw lots of SYN/ACK packets and at one point I see an RST packet then a RETRANSMISSION. I don't even know where to start to look. The reset packet, as well as all the others say Header Checksum: 0x0000 incorrect, should be...(different numbers). Maybe caused by IP Checksum offload. Does any of this help?

thank you RM

update: after looking at Fog server as src, noticed it was sending an RST with following attributes:

Length: 60, Port: random, Seq=1, Win=0, Len=0 (If that helps?)
