Map network drive does not work after tunnel configuration.

I have connected two networks through the internet using two cisco routers 1760 and a gre tunnel. Everything looks fine, but I cant map drives or it takes too long and disconnects me after some minutes. VNC is not working too, in fact, it works except the display. The screen remains black. What is happening? Is there any other way for me to connect my two separate networks and to map drives?

How are you routing between the two sites through the GRE tunnel? Are you using a dynamic routing protocol? Can you ping back and forth? How are you doing your name resolution? Do you have a common DNS server/WINS server?

Hello Irmoore.
 I have added a tunnel0 interface on both routers and I use static route. From each host on each lan I could ping both routers and after routing through the tunnel I can ping all the hosts from each host on both networks. I am not using wins or dns. For mapping I just use the host ip and the shared folder. Is there any better way to route my networks? I can map but it takes too long and in total there are about 50 hosts on both networks. One network has the ip range 192.168.1.x and the other 192.168.2.x.

You need some form of Netbios name resolution. WINS is Microsoft's preferred answer prior to Dynamic DNS in Active Directory.

Are they all one domain, or two different domains? Do you have a Windows server on each side?

Yes, I have two domains but as I told you I am not using DNS or WINS. I use my ISPs DNS. Do I have to configure one? Or if any other kind of routing is better please let me know. And another thing, I can’t use VNC but using NAT VNC works fine. No firewall configured yet.

My apologies for taking so long to get back to you.
I still say that it is a NetBios thing that needs name resolution.

The solution is either local LMHOSTS file, or WINS servers at both locations.
