This is almost certainly because there is no Computer record in Open
Directory named "DOMAIN/COMPUTERNAME$". Open up Workgroup Manager and
find the computer record that corresponds to the XP system. Add
"DOMAIN/COMPUTERNAME$" as an alias for this.

You might also have to mess with service ACLs if you are using them.
