Finally I was able to connect my Desktop (P4, XP Home) with my Laptop (Core2Duo, Vista Home Premium) thru my DLink wireless router. However the only way I can map the drives is by using the IP addresses (example: \\111.111.111\Utility). If I type the computer name I get the message “network not found”. Both computers are on the same workgroup and I can access the Internet from both computers. When I ping each computer all is Ok.

Vista has a nice network map which shows all items connected to the network. From this map I can see that the Desktop and the router have an IPv4 address and a MAC address.

The Laptop has an Ipv4 address plus an IPv6 address plus a MAC address.

When I use the command “ipconfig/all” I get all the addresses etc. plus the following which I think may be my problem:
NetBIOS over TcPIP = Disable
DHCP Enabled = No
Autoconfiguration Enabled = yes

Can someone give me a hand here and tell me what to do? Thank you

I'm running late for work - but I'd suggest that you enable DHCP for starters.

Thank you for the reply. I dont know very much about networking; where should I go to unable DHCP?

To enable DHCP you need to log in to your router. You will also need to enable NetBIOS over TCP/IP in order to browse the computers by name rather than IP address.

Thank you Ballo for the tip.

The DHCP on the router was enabled.

So I went to the properties of the TCP/IPv4, click on Properties, click Advance, click the WINS Tab and under NetBIOS Settings click the Default button (Use NetBIOS settings from the DHCP server. If static IP address is used or the DHCP server does not provide NetBIOS settings, enable NetBIOS over TCP/IP).

Now when I map my drives and type the computer name, I get connected.

Great help, Thank you

Glad I could help!
Have fun.
