Hi again
Our network is setup with a single AD domain, 1 server.
All the clients are configured in the following way: General Properties tab: Static IP address: 192.168.0.x, Subnet mask 255.255.255.0, Use the following DNS server addresses-Preferred DNS server: 192.168.0.1 (the IP address of the Domain Controller which is also the DNS server for the network), Alternate DNS server: 192.168.0.95 (the IP address of the router or 'gateway').
Click the Advanced button for 'IP Settings' IP Address is as above, Default gateway is as above with the Metric set at Automatic. The DNS tab lists first the Domain Controller, then the Gateway. Append primary ... and Append parent.. are checked, as is Register this ... the remaining entries are blank.
WINS is not turned on, and IP filtering under Options is not used.
Also, do you have a valid computer account on the server? Can you logon the server and remotely manage your computer? If not, you should delete any existing account and use the network setup disks (which you can create using the Small Business Server Administrator Consol available off the Start menu), to create a new account.
If you do this you will have to reset your DNS settings, as the Network Setup Disks setup your computer to use DHCP.
Hopefully this will help you out.
Good luck
