I got working domain with DHCP, DNS servers installed and firewall ZyWall 5 which resolves names to internet. In DHCP server configuration I've set also static IP address of server as a primary DNS server but when I try to renew IP address on Windows XP clients logged to domain there is only ZyWall IP address listed in DNS servers. This makes internet connection working but I can't login into domain on any computer vith Vista. Even with profiles which are already working well with Windows XP. And also when I try to check out comunication with nslookup, it also tries to ping ZyWall and also fails to do so as there is only Request timed out.
DNS servers not assigned by DHCP

Your ZyWall thing probably has it's own embedded DHCP server which is interfering with your Domain DNS. Disable that and you're done.
