I have 3 systems connected through Peer2Peer with single Internet connection on a Windows XP server. All is working fine, there is no problem with surfing or accessing resources. But unable to send or receive Mails through Outlook Express on 2 Systems.
Suggestions badly requested sinse my work is hampered.
I would suggest that you go to the one that works ok, click Tools/Accounts.
Go to the Mail tab, click on the email account, and then click on the Properties button
Make a note of the settings on each of the 5 tabs.
Go to each of the non working machines and set account properties match the working machine.
(Obviously if they use different accounts, you will need to adjust thinks like e-mail addresses, account names and passwords to suit)
