I already mentioned (may be not explictly) that the netowrk is established normally, the machines has its valid IP (obeying the DHCP IP range and mask), pinging working very well, the Laptop can access the internet through the PC brdige, almost every thing from the point that machines are correctly connected is OK. It is just that the intranet sites are not accessable, I just doubt that it may be related to the gateway and DNS configuration. It's like the http request might be passed through them and never get to its destination. I also knew about existance of routing table in the system, I donno much about it, but it might be a way to solve the problem if it was the gateway. I just don't get any info about the routing table and if it related to the problem

GetParent will give you a pointer to the parent dialog CWnd class. You can then cast it to your dialog class. CParentDialog* pParent = (CParentDialog*) GetParent();
