After upgrading? windows xp pro to xp sp2 I am having some strange dial-up problems. 1) I can connect and within 5 minutes the dial-up network icon disappears but I am still connected. They only way to disconnect is to restart the computer. 2) Other times I can connect check email, etc. and click dial-up icon and choose disconnect but the icon stays in tray. Only way to disconnect is to restart. Trojan, bot, etc? I do have/use/update adaware, spybot, spywareblaster and Mcafee antispyware. Any ideas?
