OK Finally i could join the pcs to my PDC........
The solution:
1. Reinstall the Zentyal on Ubuntu Server 10.04 LTS
2. Configure only the modules that i need, in advanced options
3. My name server is "ubuntu" and the ip is "192.168.100.100"
4. Configure my range DHCP 192.168.100.10 - 192.168.100.99
5. Configure my primary DNS: 127.0.0.2 secondary: ip server "192.168.100.100" and my ISP ips
6. Configure my PDC: "empresa.sml"
7. Create a user with administrator permissions "admin" and use this for join to my PDC (This was my mistake, i used the same user for manage Zentyal interface and this does not work)
8. In the properties of network of Windows XP SP3, select the option "Domain" and i put "empresa.sml" and use my user "admin" and password
9. Ready!!! everything running
10. QUESTION: Zentyal is used to establish group policies (GPO)?
I appreciate your time and answers, in special to Josep THANKS!!
