Hallo,
heute habe ich ein geplantes Backup auf den PBS mit 10 Windows VM's ab 19 Uhr durchgeführt und Stand dabei.
Windows 10: Freeze für fast eine MInute, die RDP Connection war weg , konnte aber manuell wieder aufgebaut werden.
Server 2019: wie in letzter Woche, nur Stop und Start möglich.
Waran das liegt weiß ich nicht, völlig wahllos. Hier die Log's:
