When a DNS server is looking up an IP address for a client, and it receives a list of multiple DNS servers to query, how does it choose one? Similarly, when a DNS client receives a list of multiple IP addresses for a FQDN, how does it choose one? Is it implementation specific, or is covered in an RFC?
I know if a Windows users logs into a machine, and later that machine falls off the network, that the user can log in to the machine with cached credentials. Is there any way to precache those credentials? (Without having to log into each and every machine locally?) We use some tablet PCs in our manufacturing facility and they use wireless cards to access the network. Sometimes new users need to use the tablet PCs when they are unable to connect to the network, and can't because they've never logged into it before. It would be nice to be able to put their creds there in some automated way before that happens.
