[Samba] samba share not accesable from windows PC,s "newbie here"

[A d m i n i s t r a t o r]

Well i have installed samba on my redhat 9.0 server ..

& just to try it  made a smb.conf with the following entries ...

[global]
workgroup = SIMPLE
[test]
comment = testing only
path = /myhome
read only = no
guest ok = yes

& restart smb services .. but the problem is that when ever i try to browse
from other windows PC from the network .. i get some error like this
"account does not have access right to use from this workstation" ...

how can this be resolved ... ?
