I am in the process of setting up 10 remote sites using draytek routers and adsl connected to a watchgaurd firebox at the main site . The routers are set to do lan 2 lan vpn so there is no client software loaded on the pcs.

I can ping, connect to machines, but am unable to log onto the domain or add a machine to the domain at the remote site  end of the vpn. anyone give me any advice on this?

My guess would be that name resolution is not working over the WAN lines - what you can do is setup a WINS server, and then have all PCs from all sites use the same WINS server...or you could have separate WINS servers, with 2 way replication between them.

as a quick fix, on your PC, edit the LMHOSTS file and add this line:

x.x.x.x  <name of PDC>  #PRE #DOM:<domain name>

and then reboot

that should let you login to the domain.

Thanks for the response, I had already set up one wins server at the main site, and it works as far as it is resolving machine names to ips. tryed renaming lmhosts.sam to lmhosts and adding in 10.110.150.4 EMC24  #PRE #DOM:EMCUK and still had no luck.

Is NetBIOS enabled over TCP/IP?

Check the clients at the remoter site. Check their WINS properties in TCP/IP and make this change.

Also I have seen on some VPNs where you enabled NetBIOS over IP in the VPN config screens.

The remote clients are receiving the WINS server IP address in their TCP/IP properties as well arent they?

netbios over tcpip is enabled and the wins server ip address is correct. there are no settings on the router for netbios over ip.

just relized that by putting x.x.x.x  <name of PDC>  #PRE #DOM:<domain name> in the lmhosts file, it does enable me to log on to the domain, but still does not allow me to add a pc to the domain. anymore ideas welcomed

Does the server have itself listed in its TCP/IP properties as the primary WINS server? (if it is the WINS server that is).
