Network Path not found. Couldn't copy your roaming profile....

hi,

i need a some help here.
here's the background on my network: i have 3 NT4 servers
running in my company in a single domain.one of them
serves as a DNS server. recently my company bought a
Windows2k3 standard server. i installed and ran it as a
DC with AD and DNS.
i created new user accounts and configured them to be
roaming accounts, but when ever i tried to log into the
server, the clients wouldn't be able to find the network
path where i saved the profiles.
i've set the necessary NTFS permissions and shared the
folder storing the profiles, with Everyone having FULL
Control.
i could at first log into the server using the roaming
profiles, but once i reboot the clients or servers, the
path becomes unreachable.

can anyone give me some clue as to what is wrong with the
configurations??

thanks in advance.
