Vista not finding other computers / workgroups

ok, so I will admit I am not a genius but I am pretty good at computers so
don't hold back

we have two vista machines trying to connect to one xp machines "my
documents' (sharing is enabled on all) I have set the workgroup name to
HOME-TARA on all pc's and the routers wireless name is this (is this causing
a problem? didn't work if I changed it though).

however at one point it found them then after a restart it disappeared.

another problem is that the workgroup name wont stay changed from WORKGROUP
to HOME-TARA or anything else it says "windows needs restarting in order to
apply your settings etc" so I click ok it restarts then it has renamed it
self back to HOME-TARA no matter what (unless I don't restart)

last and final thing when they were viewing each other it asked for a
password to connect to it? none of the machines had/have a password on them
ever except the 128 WEP and the wireless

if anyone knows how to sort this PLEASE tell me ... beacuse you are
obviously better at computing than me!


Thank You in advance
