I have a pc running windows xp and it is in domain. I have attached a Hp laser printer for my pc and shared it. But now other pc's cannot connect to the printer until I have run the services (net logon, server, shell hardware detection) in administrative tools. However my problem is the services(net logon, server, shell hardware detection) will automatically off when I logon to the machine on next day. Then again the other computers cannot connect to the printer. Is it a virus attack??????? and What should I do1 person needs an answerI do too
