I am attempting to execute commands on remote machines in our network. I have successfully used psexec for this task, but I am running into an odd performance issue. psexec takes a long time to actually establish and run commands on remote machines (~30 seconds).
I originally thought this was a DNS issue, but the problem exists if I connect to the host using a domain name or an IP. I have added the remote host name to the etc/host file, but that has not helped. From a wireshark capture, I can see several attempts to connect to the remote machine on port 80 for some reason before my machine attempts to use more normal ports such as 445 or 135.
