Further to this.
We've got it (mostly) fixed. If a client can return to the office, it fixes itself automatically. Not everybody can do that currently, so we have a manual fix for those who can't connect to Corporate Network over direct access. Problem is, it requires a local admin password to run. Because of course it does.
Retrieving the password and copying the scripts and accompanying data is easy enough. But often, the only tool we have that can actually remote access the affected computer is Skype for Business - we have to send them a Skype message and get them to present their screen.
The problem with that is that the presentation suspends when the computer prompts for the admin password. This is a standard limitation with Skype, and there isn't a workaround. We have to read the password out and get them to enter it.
Here's the rub: it's a strong password. And I mean STRONG. So this is what it's like:
"Okay, ready? Capital T, full stop, dollar sign, lower case G, numeral 3, plus sign, backslash that's the one above the enter key, lower case U, lower case B, capital Y, left curly bracket..."
Left curly bracket!. It's a bloody nightmare is what it is.
At least it works 100% of the time.
