Hi,

As it says about an ASP.NET issue, do you have an option to re-install .net?

Yes. I try reinstall .net 4.5.2 and register with aspnet_regiis. No success

Hi,

Make sure that you registered the ASP.NET in correct folder location and using the command: aspnet_regiis.exe /iru. Also, make sure to restart the server

I'm try

C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe /iru and reboot

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe /iru and reboot

No success. Always error "Could not load type 'CafeSettingsIni' from assembly 'Microsoft.Exchange.VariantConfiguration". I'm try .NET 4.5.2 and 4.5

Hi,

I suggest to use the Setup /m:RecoverServer switch to rebuild the Exchange server. Most of the settings for a computer running Exchange 2013 are stored in Active Directory. The /m:RecoverServer switch rebuilds an Exchange server with the same name by using the settings and other information stored in Active Directory.

Refer from:

Best Regards.

This is the last option that I wanted to use. But it seems necessary.

Hi,

Actually, I won't provide this suggestion unless this is necessary. I saw many other same errors and issues, solutions are all recovering exchange server.

Best Regards.
