Small W2K3 network - 20 users (XP Pro)
All Outlook users functioning fine except one.
This user cannot SEND mail (550 not local host rcwa.net, not a gateway), but can RECEIVE mail.
Outlook settings are correct (incoming/outgoing POP3, account name/password, authentication, etc.)
When I try to TEST ACCOUNT SETTINGS the error states a network error/cannot connect to the Internet - however, the user can browse, ping known sites (i.e www.yahoo.com
, et. al.) This machine can ping the servers and other workstations.
TCP/IP is the only protocol and it uses DHCP for IP and DNS.
