I have a DS3 plugged into our 4510R Cisco Switch that is shutting down for now apparent reason... i use the CNA client, and the only issue i see is when i look at the Graph\dropped packets and errors, is see 8mil errors...
i ran an analyser to view the errors, and
i get following checksum error
TCP 51480 > http [ACK] seq=185 ack=3353 win=63935 [TCP CHECKSUM INCORRECT] Len=0
