I have several computers. Four in fact. Three are laptops and one is a desktop. Two of the laptops use Vista and the other is XP. The sole desktop is XP. I have set-up a home wireless network, sharing a single printer. Up to a few days ago everything worked quite well, a few glitches here and there,but in all pretty darn good. My wife has a small Dell laptop that works fine at home, she can send and receive emails as usual. She travels alot and has never experienced any problem before last week. Her laptop is unable to send emails to anyone except those addresses within the same internet provider (Time-Warner, Roadrunner). I have searched thru her Outlook Express settings several times,checked firewall settings,cleaned out junk files and even cleaned out and defragged her registery. As well as virus and malware,adware scans (with Kaspersy Internet Security). Everything works great at home until she goes out of town or to a friends house and tries to send out email, it fails to work. I’m stumped. Can someone lead me in the right direction for a fix? Thank you.
