We have 5 computers all networked with LAN cables. Computers B,C,D and E all access a dial up modem to the internet via computer A. Up until recently, all worked well. Now computer B whilst able to access all the other computers in this home network, is unable to access the internet.
Computer B can see the dial up network connection, as connected, as well as the local area connection, but internet and email are not available/accessible.
Have replaced the Lan Cable, disabled the firewall, checked internet connection sharing and run anti virus AVG.
Computer B - as are all 4 other computers, is using Windows Home XP Service Pack 2.
What else can we do?
Please can someone help.
