LanSchool cannot access AD controller?

[googlemad]

Getting a weird message this morning with LanSchool Teacher about how it cannot connect to AD controller...working fine before Christmas!

 

Any ideas?

I've had similar before I left my last company.. Sure the cleaner hadn't unplugged what ever server etc AD is sitting on? Sounds silly but it has been found before.

We restarted the secondary AD controller which seemed to sort the problem out - One of those post Christmas mysteries I suppose!
