Server 2012 R2: .NET framework does not work
Posted on 2016-09-06
I am facing issues with .NET framework 2 or possibly 3.5
A production RDP server showed THOUSANDS of app crashes after the installation of a static database (phonebook-style) on friday. Administration tools such as PowerShell, Server Manager or certain Snap-Ins for MMC cannot be started. The machine boots just fine and runs applications such as Office or browsers without complaint. Eventlog cannot be opened.
Support of the presumably offending applications shrugs off all help. No issues are known. Support of Datev, a popular and complex German bookkeeping software suite sais only that .NET framework seems to be damaged, which I already knew.
I am finding many tools to download, install and repair .NET framework, but none of them seem to apply to Server 2012 R2, where .NET framework is a feature of the OS and is not installed from downloads.
Is there anything I can do other than reinstall? No backup, unfortunately.
