We started this month to get this error when opening the NAV RTC:
[Microsoft][ODBC SQL Server Driver]Cannot generate SSPI context State ID: HY000
I've seen https://www.sauravdhyani.com/2012/04/navision-cannot-generate-sspi-context.html
But the host file fix does not seems to do anything for us. I then found, it may be a network / domain or time issue. Or issue with our antivirus.
I've fixed the timing issue. SQL, NAV and client terminal server running same time. And disabled antivirus.
But still once in a while, like once a week, some users on the terminal server is getting this error.
Just today only one (1) user got this error while others was using NAV normally.
NAV version: 6.0.35003.0 / 2009
Terminal server: 2012 R2
Any ideas on how to debug this?
