This is very true. There are thousands of possibilities out there that can cause similar issues. To those out there with the same issue, if you try Mobius' "fix" and it doesn't work for you, don't blame the command as it could be any number of reasons causing the issue.
Especially since everyone's servers are different from hardware and BIOS to network/internet stack and settings. Since I am reusing an older Dell OptiPlex that work gave me during our last PC refresh, I have a second one that's exactly identical since we purchase these machines in bulk and will see if the same issue occurs and if the same command fixes it. Maybe I'll get lucky and it works right off the bat or maybe I'll have to send the command again. If the results are the same knowing the variables are the same then it COULD be hardware related. Only way to really tell is to wipe this machine and try again on a different network/internet provider.
