CAN NO LONGER CONNECT XP TO VISTA

Old, established, stable, working network of 2 Vista (32) and 2 XP home.

Two Vista computers can connect to each other and to two XP computers. The
two XP computers cannot connect to either Vista computer or each other. All
four can connect to internet (not router). Heard rumor that Vista security

Suggestions?

Vista?
