I an trying to connect a Win 2000 desktop with a Vista notebook.
I use dial-up mode, so this is only for file and print sharing, as well as a wireless access point for the notebook.

Earlier today, D-Link guided me thru the set of the router, but then left me high and dry.

We got to the point where the notebook could ping both the desktop and itself, but the desktop timed out when trying to ping the notebook.

The network on the notebook sees only itself.
The network on the desktop sees only itself.

Both computers are using the same workgroup name.
On the desktop, I assigned Yadda as the network id.

On the Vista system, the connection list includes:

Yadda Waiting for users to connect
Yadda Security-enabled network
MyWireless Security-enabled network

PLus a few other networks, likely belonging to my neighbors.

What do I need to do to get this working?

ALL the drives on the Win 2000 system appear to be set for file sharing, and I believe that the Vista drives are too.

Am I running into a security software issue?

Desktop has Kasprsky AV 7, notebook has NIS 2008

Is there a step by step guide for the networking disadvantaged?
