Adobe Creative cloud 2017 slow \ crashing on launch

[Zourous]

We've had a big network lag for some time now (since the summer). The lag seems to last a while (best part of an hour) and goes again. It doesn't happen every day, but when it does happen it probably only happens once day but at a random time during that day. I know, not much help.

 

When this happens the biggest report we have is that one of the adobe products isn't launching. We're talking whole classrooms of students with frozen screens. Once and if their adobe product loads, it is fine. They load it on another day and it is fine, no issues. I'm guessing the adobe software is checking it's license over the internet in part of the launching process. Does anyone know if it does this each and every time or whether it could be every few days?

 

Or has anyone had problems of this similar nature with CC 2017. At the moment the lag is crippling a lot of IT lessons and I think the IT teachers are going to throttle us before long.

 

I've looked for other network factors but nothing is showing up and I've heard Adobe support is not good, so I thought I'd try here first.
