Microsoft DNS error 4000 and error 4007
Recently we had “Patch Monday” – unusual since we usually patch on Fridays (in case something goes wrong we have weekend ahead), but this one time was good opportunity since there was some infrastructure work and we had planed downtime and we took the opportunity to patch.

Exchange ECP / The LDAP Server is unavailable
“Topology Provider couldn’t find the Microsoft Exchange Active Directory”

Windows Server 2012 R2 with Exchange freezes on Hyper-V Integration Services Update
