I am getting this error, "cannot generate sspi context" when I try to access MS SQL 2005 via Windows authentication over a Juniper VPN connection and if I am NOT connected to my own company's vpn. I am logged into my WinXP2 Notebook under a different domain (my company's domain, whereas the SQL server is on a Client's domain).
More info: If I connect to my own company's VPN using Windows VPN connection, I do not get the error (so this is not a super urgent problem - just annoying and puzzling). Also, I believe I only started getting this error when I started using my domain login on my Notebook as the administrator of that machine (i.e., I am not logging into my company's domain at all in that case.)
I am a database guru, but networking is still a mystery to me - I have found references to "kerebos" and have no idea what to make of that.
