Is it possible to add computer from remote location to AD (windows 2008R2) and enable user login?
I've run DJOIN as described here:

but cannot login into domain after doing this, because my computer doesn't recognize my user.
I get "there are currently no logon server available to service the logon request" error.
P.S. I don't have VPN connection.
You'll need to establish a working connecting to the domain to log in as a domain user - at least for the first time, subsequent times may be able to use cached credentials if they're enabled.
You should probably log in as a local user, establish a VPN connection, hit 'switch user' and log in as a domain user.
