Problem with LAN and LAN internet sharing.

Hi guys.I have some problems with LAN on two PCs with Windows 7.
Host PC - windows 7 professional x86
laptop - windows 7 ultimate x64
On my HOST pc I have two network cards,on one i have internet connection(cable) ,with second I'm in LAN with other PC.
I configured IPs,i configured ANSharing,i put both pcs on same workgroup etc.
Problem is that sometimes LAN and internet on other pc WORKS,but sometimes and most of the time it doesnt.
When it doesnt i can see pc in LAN,but i cannot access...
I tried everything...and it didnt help.
In connection properties on HOST pc IP is 192.168.137.1
On other its automaticaly and DNS server is the public one 4.2.2.2.
When im trying to troubleshot problem,sometimes it says DHCP is not enabled,sometimes that modem isnt connected etc etc..

Can u tell me some of urs solutions pls?

Do you use a switch or a hub for your LAN...

Or do you let your laptop use your internet connection on your HOSTpc...

Yes i shared internet connection.
As i said i have two lan cards on my pc.
One is connected with cable modem,other is connected with laptop.
When my pc is power on,laptop has internet.
That worked fine with other pc two months ago.But then roommate bought new laptop and sold old pc.And now with that laptop i have these problems i've explained.
Sometimes internet and lan works,but sometimes just stops...Every half an hour.

Can you take a screen shot of your network configurations using cmd and utitlity ipconfig/all on your HOSTpc.

If possible take a screen shot of the same thing from your laptop, take the image on a flash drive, upload to HOSTpc and post here.

Can you post your HOSTpc config again, some info is missing from the top.

Such as IPconfig and Ethernet adapter LAN config.

your client one is fine.

If you can setup you DNS server in your laptop to 192.168.137.1

Test connectivity.

Try to ping your HOSTpc at 192.168.137.1
