Greetings! On a network of only two machines (1 laptop and 1 desktop), both running XP Pro SPII and linked through an ADSL modem router, both machines have developed an irritating slow down in performance. The desktop acts as a server (in truth a file store) for both machines. An example of the problem is that if one user is typing into Word on one machine and another is typing into an email, both machines feel as if they have to wait for the other one before the next keystroke is accepted. There are no reports of errors on either machine, network or otherwise. Both machines run Kaspersky IS 2009 and are new within the last 12 months. Any ideas, anyone??
