Today I had another problem that almost made me despair. I'm supposed to migrate an Exchange 2013 environment to Exchange 2016. Not difficult so far. But Exchange 2016 cost me a few more gray hairs today.
Error:
During the installation or the schema extension, the Exchange Server displayed the following error message:
An unexpected error has occurred and a Watson dump is being generated: An error occurred while reading the file „C:\Windows\Temp\ExchangeSetup\bin\EnterpriseServiceEndpointsConfig.xml“. The error was „There is an error in XML document (1, 1) . Additional information: „‚.‘, hexadecimal value 0x00, is an invalid character. Line 1, position 1.“.

Solution:
The problem was due to a defective Exchange ISO file. I downloaded it again from Microsoft and then ran the schema extension again. It then went through without errors.
If you receive this error message, simply try a new ISO file.
