Leave Domain: “A general network error occurred’

KB ID 0001738 Problem After a recent lab on the test bench, I ended up with a 2008  x32 standard server.

O365 with Duo MFA (Without a P1 License?)

KB ID 0001737 Problem Working for a cloud service provider, (and a Duo partner). I get a lot of queries about Duo MFA for Office 365.

FortiGate Securing Remote Administration

KB ID 0001734 Problem When considering Securing FortiGate  remote administration, I’ve written about changing the https management port to something other than TCP 443 before, I suppose that’s security by obfuscation (though even a script kiddy with one hours experience, will be able to spot an html responses).  Typically with other vendors you limit remote administration access, to specific IP addresses (or ranges).
