I used a BSNL broadband bussiness 3000 plan for multi user environment. Our Computer centre setup a 40 node with Windows 2003 server in Client/server configuration.

my Setup :

We used a ZX DSL 531B modem. My connection setup to d-link 16 port Swich in Uplink port. Additional two swich connected each other.

i set a Defalt gateway is 192.168.1.1 in all pc in network include server too.
Ip rang of client is 192.168.1.2 to 192.168.1.99
DNS setup of server IP is 192.168.1.100
Preffered DNS setup of all client is 192.168.1.100

Status:

Broadband working OK in All client PC (Node) but not working on Server.

I have problem with.....
1. 192.168.1.1 site not working.
2. Internet not working in Server. (Which have windows 2003 OS)
3. How to control Wireless clint and restrict more connection as well as setup.

Need a help regarding above problem as soon as possible.
