If I remember correctly XP Home can just join work groups, it cannot fully connect to a network that uses a domain controller - hence me not being able to see files in the office when connected remotely! GRRR.
Nothing preventing you passing domain-valid credentials and mapping drives on a domain...
Domain = BIGCOMPANYDOMAIN
User = PCUSER1
When you map, pass the /USER:BIGCOMPANYDOMAIN\PCUSER1
credentials and Bob is, as they say, your uncle.
===========================
Andu,
WRT the original problem above, can you map a drive using a dotted IP address rather than a computer name?
EG:
PC1 has IP address 192.168.1.1 and hard disk C shared as "C_Drive"
PC2 has IP address 192.168.1.2 and hard disk X shared as "X_Drive"
Try mapping PC1's disk from PC2 by typing, from the command line, the following:
net use \\192.168.1.1\c_drive
That will tell you if:
it can see it
you have permission to share it
Both of these are quite important
