Mixing IP addresses over 2 x NIC's

I have just taken over a Server 2008 Std that currently has 2 NIC's configured as:

#1
Description: HP NC362i Integrated DP Gigabit Server Adapter
Physical Address: 78-E7-D1-F5-A9-B0
DHCP Enabled: No
IPv4 IP Address: 10.26.213.130
IPv4 Subnet Mask: 255.255.255.240
IPv4 Default Gateway: 10.26.213.129
IPv4 DNS Servers: 196.43.6.30, 196.43.42.190
IPv4 WINS Server:
NetBIOS over Tcpip Enabled: Yes
Link-local IPv6 Address: fe80::942b:af7c:c15b:3262%10
IPv6 Default Gateway:
IPv6 DNS Server:

#2
Connection-specific DNS Suffix:
Description: HP NC362i Integrated DP Gigabit Server Adapter #2
Physical Address: 78-E7-D1-F5-A9-B1
DHCP Enabled: No
IPv4 IP Address: 192.168.4.1
IPv4 Subnet Mask: 255.255.255.0
IPv4 Default Gateway:
IPv4 DNS Server:
IPv4 WINS Server: 192.168.4.1
NetBIOS over Tcpip Enabled: Yes
Link-local IPv6 Address: fe80::695f:4132:705c:c0bc%11
IPv6 Default Gateway:
IPv6 DNS Server:

Now I am aware that having the NIC's with different addresses is not really a good idea. Especially with DHCP on the server enabled and DNS.

However the #1 NIC connects via a VSAT link with a set IP Address  10.26.213.129.

The problem I am currently having is that users cannot access the Internet but you can direct from the Server.  

Any suggestions on improving / resolving this situation?

10.26.213.129 is your default gateway on the Server.
For the users to see the internet, they would either need to point to the same default gateway or pointing to the server with Internet sharing or a firewall configured to re-route traffic via the default gateway.

The PC's are currently set as 192.168.4.34, 255.255.255.0, Gateway 192.168.4.1, DNS 192.168.4.1

1) you cannot use the VSAT NIC Default gateway on the other segment
2) ICS (Internet Connection Sharing) have issues if you have static addresses.
3) considering Internet comes from the VSAT you'll be forcing your Server to act also as a Router, depending on your traffic probably this is not a good strategy.
4) The long delay of the VSAT links put an extra stress on the routing processes.

If I were you I'd try to use a small external router keeping the Server with just one NIC.

Sorry for the delay in getting back to you been at the coal face so too speak.

Ok, your comments are fully justified and taken into account for further setup. However I have resolved the issue by disabling the RRAS and then enabling it and as you know you then have to re set it up. Did this and hey presto all the routes are correct and the users now have access to the Internet. It would seem that a previous tech had loaded Endpoint on the Server and this is where the problem originated. What Endpoint did to the RRAS, I do not know. But it was 'fixed' by doing the above.

Thank you for your comments and I will take them into account when we set this up correctly.

Regards

The error was resolved by reloading the RRAS.
