Hi, I currently have a problem with MBMC installed on a 2012 server (we are a new reseller and testing the MBMC before deploying MBES for our customers) : - Server has following roles : IIS, secondary DC, secondary DNS, backup DHCP, WSUS (with SQL 2012 R2 Express not internal database) - MBMC installed with SQL 2012 R2 Express, all went flawlessly, we can access the console, update policies, deploy clients, viewing reports, etc. The problem is with Windows Backup, every backup failed ever since MBMC was installed on the server. I tried different things, but it appears to be a bug with the VSS System Writer disappearing (addressed by MS, but the patch doesn't work on 2012) : VSS fails to create a snapshot for backup when there are more than 1000 folders/sub-folders in the .NET folder (C:\Windows\Microsoft.NET, currently I have 1827 folders). I managed to delete some folders (down to ~1500) and the backup was OK. But every time I view reports, folders are generated again and backups fail. I know for sure that our customers will have the same problem with backups (they all use Windows Backup or third-party app that use VSS), does anybody have this problem? Is there a solution to this?
