Estação WinXP trava e não acessa compartilhamento do samba

[CRBS]

Olá!
Possuo uma rede com um servidor Debian 4.0, e samba 3.0.25b com autenticação via LDAP. Nesta rede tenho umas 30 estações WinXP Professional SP3. O problema que tenho ocorre quando estou em uma estação winxp e tento acessar os compartilhamentos do samba no servidor, algumas estações não conseguem acessá-los, sempre após termos feito a autenticação do usuário, digitando login e senha. Não sei se o problema está no ldap, no winbind, em alguma configuração do samba, ou nas estações winxp.
