I have lab of 31 pc including the teacher pc. I have some problem with some of them host unreachable. However i able to power on those computer which were host unreachable. Only the 1st 12 PC i install on able to view the thumbnails in the teacher applications. while the other were unreachable. I already tried changing the tcp/ip limit to 50 but still the same. Anyone have solution?
