Open Command-Line-Box (cmd.exe) with Administrator-Rights.

C:>netsh int ip sh int

Idx Met MTU State Name
--- --------- ---------- ------------ ---------------------------
1 50 4294967295 connected Loopback Pseudo-Interface 1
11 10 1500 connected LAN-Connection
12 0 1350 disconnected LAN-Connection* 9

Search the virtual Interface from Check Point Endpoint Connect. It is the Interface with Metric 0, MTU 1350 and an asterisk at the name – at this example “LAN-Connection* 9” -.

Now set the first DNS-Server o your remote Domain for the VPN-Connection – normally it is the Active Domian Controller (here for example 10.0.0.1) on remote VPN-Network –

C:>netsh int ip set dns "LAN-Connection* 9" static 10.0.0.1

To add an secondary DNS-Server and so on use following command:

C:>netsh int ip add dns "LAN-Connection* 9" 10.0.0.2

Now check settings:

C:>netsh int ip show dns

On the same way you can set the WINS-Servers of your Domain. You have to use wins instead of dns on all commands.
