Question : Cannot map a network drive

Hi,
This is the environment:

Desktop Vista 64 (computer name = Daddy) (hardwired to the U-Verse Residential Gateway (RG))
Windows XP Pro Wireless
Windows XP Home Wireless

All 3 systems in same workgroup
All 3 systems are identified by RG
All 3 systems can access the Internet

XP Pro can access the shared files sitting on Desktop Vista 64
XP HOME CAN NOT ACCESS THE SHARED FILES ON DESKTOP VISTA 64.
I tried (from the XP Home system) to map the network drive:

Window Explorer > Tools > Map Network Drive
 In the file box, I put \\Daddy\XP_n_Vista_Documents_On_G

Received error message:
"The mapped network drive could not be created because the following error has occured:
The network location could not be reached. For information about network troubleshooting see help"

I am pretty technicle (albiet not networking), and this on is stumping me.

Need some good help here.  Thanks in advance,

Bob

 
 

Answer : Cannot map a network drive

Can you turn off the firewall on all the computers?
When you ping the Vista machine are you pinging "daddy" or the ip address? Does it ping the right ip address when you ping Daddy?
