joining domain windows 2003 through Mikrotik

RouterOS General
1

I have remote office LAN with Mikrotik as gateway
this is one side

Also i have central office with domain controller windows 2003 inside it and mikrotik as switch there

Then, there is provider’s VLAN connection between remote Mikrotik and central office Mikrotik (was created bridge)

I tried joining central office domain from remote office PC through two mikrotik but i cannt do it

i have DNS record of central domain in the remote office DNS server, Ping is okey and i connect any network drive of central servers through both mikrotiks

But joining domain is impossible!

Does mikrotik allow passing through itself packets of windows’s authenitifications, when joining domain?

Or only if i start PTP VPN on Mikrotik and in this case i can login into central office domain

Unless you’ve changed the default setup, the firewall should allow anything through from an internal LAN to another internal LAN. Since it sounds like your provider is VLANing your two offices together, you theoretically should be able to do this, but I’d imagine that your VLAN connection is over your external interface, so the firewalls at either end will block incoming traffic. Establish a VPN tunnel between the two Mikrotik routers and you should be good to go.
