Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I cannot connect clients to sbs2003 domain because of this error: The format of specified network name is invalid.

Before that there is a prompt for a login and password, so the server is found. I can't also view the server resources via \ \ servername or \ \ ServerIP because it can not find the path. I can not add the computer account by servername/ConnectComputer because after entering the login and password I can wait forever.

Clients can browse the web without any problems with the DNS server address - sbs2003.

nslookup servername gets the correct server name and the correct IP address. Pings to the server works without a problem.

Gateway / router / firewall for the network is debian, also DHCP Server. The topology is as follows:

modem - debian - lan where there are clients and the server SBS2003

Client gets the following configuration from DHCP server:

Connection-specific DNS Suffix: domain_name
IP Address: 192.168.20.100
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.20.1 - network interface on Debian
DHCP Server: 192.168.20.1
DNS Servers: 192.168.20.2 - SBS2003 server address
Primary WINS Server: 192.168.20.2

For the SBS:

dhcp service uninstalled

One interface

Interface configuration:

IP Address: 192.168.20.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.20.1
DNS server: 192.168.20.2
WINS Server: 192.168.20.2

DNS configuration:

forward here where I have entered OpenDNS DNS addresses

is set to listen on all IP addresses

So once again the internet works without a problem, client gets addressing from a DHCP server, on the client does not work server shares or connecting to a domain. Somebody help me because I no longer have the strength to go further.

Host names are not allowed underscores... Or is the underscore just for demonstration purposes? If not I am not entirely sure how you managed to set up your SBS domain with an underscore but be prepared to bin your SBS build and do it with a standard domain name. Also try choosing a meaningful domain name.

What is the domain name you're trying to enter? As it's the cause of the error you'll have to include it in your question to get an answer. –  Alex Berry Jul 27 '12 at 11:48
    
and is the dns suffix domain_name or domain_name.tld? It should be the latter. –  Alex Berry Jul 27 '12 at 11:52
