Hi there, First off, I'm running the following: MacBook 2GHz Intel Core 2 Duo (black) 2GB 667 MHz DDR2 SDRAM Mac OS 10.4 Parallels 3, build 4560 Guest OS - Windows XP Home Network configurations are as follows: On the Mac: Location - Work (All configuration works fine on the Mac side including email(Mozilla) - Windows the Internet works only not email) Using the Built in Ethernet - IP: 10.x.x.x Active and connected Parallels NAT - IP: Same as above Active and connected Airport - Not active Location - Home (All configuration works fine on the Mac side - Windows the Internet works only) Exact same as above Have also changed these settings to DCHP without consequence On the Windows side: Network configuration is set to 'Obtain IP automatically', and 'Obtain DNS automatically'. I have narrowed the problem down to configuring Parallels based on this: - email works fine on the mac side when I working at my Work location - I used Mozilla to discover this - only internet works on the windows side -Mozilla doesn't even work on the Windows side ... so it's not my Outlook program. Outlook used to work, where I could send and receive. When I'm at HOME and try to access my work email account through Outlook, I can receive only - not send. When I'm at WORK and try to access my work email account through Outlook, I can't send or recieve. Please help. Thanks in advance.
