15 days ago I began to have problems with a network of 16 computers and 8 printers, all the computers stopped printing, basically a hp 1150c and a hp lazer jet 6P, I try to reinstall Windows 98, that solve the problem during 2 to 3 days, I also try to install one of the printers in a server Dell with NT 4.0, and the same thing happened, It worked for 2 days, I try to change the one wired and hub of 10/100 at 100/100 without any result, all the computers have mcafee antivirus with a connection dedicated to the Internet.

Does somebody have some idea?

Thanks <IMG SRC="smilies/frown.gif" border="0">
