User name and password

I have a wireless network, which consists of a PC laptop, a PC desktop, and
two Intel-based Macs. I can access the shared folders on the PCs from the
Macs just fine, but I cannot access the Macs from the PCs. The reason: the
PCs demand that I supply a user name and password, and although I supply what
I think is the correct information in the correct format, my request to
connect to the Macs is disregarded. How can I find out what my correct user
name and password are? Will I have to set up the network again?

Hi
I an do not know anything about the MAQc aspect.
For the PC this can Help.
Successful Sharing involves some general consideration in Network
settings,http://www.ezlan.net/sharing.html
As well as specific adjustment of each computer according to what it is
allowed to be shared.
