Reading through that has given me a headache...it's too true.
my weeks sysadmin nightmare working remotely
I just spent half a week having an email back and forth with someone who insisted a system didn't work regardless of it working (and being shown to work through screen recorders and tutorials) with every variant and setup under the sun.
After finally convincing them to let me setup a remote desktop connection to their computer to see first hand, we did the run through and, surprise surprise, it worked perfectly. They just read a single (something they had written) word wrong and thought they were in the wrong place. If they had even filled in the "problem report" form provided they would have seen their own stupidity.
Love that we're back to weeklies, have a beer on me!
