Yes, I checked them and found nothing that indicated any problem with 
networking.

Using samba that works just fine at 100Mb/s network speed.But, when I try to 
read my Explorer stops responding. Seems like related to my problem !!!
This could help me further.

Not a nice option, I'd have to move a lot of hardware. Anyways as a last 
resort I will try this.

No.

Done. Seem fine but I was wondering about MTU as mentioned in the other reply. 
I can't find such setting for my network adapter (rtl8139) in windows.

Done many times and should be fine.

I removed my firewall and just use basic NAT. still the same problem exists.

I tried that but messages from these programs are not that easy to read and 
translate to the specific problem I'm having.
I guess I'll have to do some reading.

Thanks for your reply,
