If you are using DHCP on your server you must reserve the fixed IP that your client is using.Also you need to set your subnet masking to enbale your server to see the client.

Hello

I didn't understand completely because couldn't understand what is 172 serise? or how your 50 clients conenct to the server...

From what I understood it that you have 2 different networks and would like to try to join them.

Add two network cards to one computer.
network card A goes to the 172.x.x.x network and Netowrk card B goes to the 192.x.x.x network. On network 172.x put the gateway as network card B and on network 192.x put the gateway as network card B.
By this time, they should be able to communicate...

hope this helps

I have no idea your user wants to change his IP address and why would you allow him to do so, but if you agreed if something else. There are different ways to do so, if you want you can setup another computer and do a NAT (Network Address Translatoron it), if you have a Proxi Server it can do it, is a little complicated but it works, also you can use WinRoute, it is very simple to configure. If you want set it up and need some help just e-mail me and I'll help you.
And the easiest way to resolve this situation is just Go to Control Panel, Network, Protocol, TCP/IP Protocol, Advanced, on IP Addresses click Add, then type 192.1.1.99 (just give the server one 192.1.1.X address), give it a subnet Mask, click Ok until you reach Control Panel,then it will ask you to reboot the server.
Just restart the server and when it boots up give it a try, you can try to ping the any workstation at the segment 172 or your other workstation at the segment 192.
It will work,
Good luck,

Try giving your Client's PC the same Subnet Mask address as in your existing LAN. This should work.

Good luck. @Uch

One way to do it is add one IP address to your Server Lan card as 192.1.1.2 in network neighbourhood, IP Properties, Advanced.
Then change IP of the client who needs new IP to 192.1.1.1
Thats all. Server NIC's can take up lots of IPs. Now your client will get authenticated & come onto your domain.
In case you use Proxy Server, you need to add the 192.1.1.1 to 192.1.1.254 in NAT table as well, else internet access will be denied to the client with 192.x.x.x IPs.
Hope this helps.
