What version of client?
What precise options were chosen during installation, if any?

If you installed as a SecuRemote client, DNS won't work unless the gateway is configured correctly, see: https://community.checkpoint.com/t5/Remote-Access-VPN/Quick-Primer-on-How-to-Configure-your-Gateway-for-SecuRemote/m-p/79081#M2717
If you installed as either Endpoint Security VPN or Check Point Mobile, you should have been assigned an internal DNS server on connection unless there is a misconfiguration somewhere.

If you installed as SecuRemote, try reinstalling as Check Point Mobile instead.
If that doesn't work, you need to work with whomever maintains the Check Point gateways you are attempting to connect to.

Sounds like you can connect to the VPN site itself, just cant resolve the host by name once connected. If thats the case, please check settings I will put in a separate post here, as soon as I find them in smart console.

K, here it is. IF what I said in my first post is true, make sure (or whoever has access to smart console) that what I pointed out is selected to your company's INTERNAL dns servers, NOT google dns, which is what I have (mine is just a lab, thats why)

Cheers,
