I recently migrated from Win 98 and Outlook 97 on a Dell P2 to XP and Outlook 2002 on an HP P4. I moved my DirecPC PCI Satellite Receiver card over as well. With the DirecPC Satellite PCI card, I can use the Bell ExpressVu satellite service for downloads (uni-directional, dial out, satellite back). Bell Sympatico is my ISP, and regardless of which dialer I invoke (Windows XP or DirecPC Navigator), I always dial the same provider, same username and password. The only difference between the two dialers, is how the packets are treated. DirecPC Navigator dials my service provider (Bell Sympatico) and sets up a tunnel from my PC to the Bell ExpressVu server, so that it appears all requests are coming from ExpressVu. All packets destined to my PC are then sent back to ExpressVu, up to the satellite and broadcast back to me via the PCI card in my PC. This worked without a problem for two years with Win 98 and Outlook 97. Since migrating to XP and Outlook 2002, I have discovered that I cannot send mail with an attachment (any size) when I am using the DirecPC Navigator to dial (and thus use the satellite service). It seems to time out. I have no trouble sending mail without attachements though. I have the same issue with Outlook Express. I can however, use the Windows XP dialer and connec to the same service provider, with the same username and password and send attachments via Outlook that way. A workaround, but not a viable long-term solution. I have installed the latest Office and Windows XP service packs and I am using the the latest DirecPC Navigator software (same verison I was using on the old machine). I have disabled all firewalling. Since it uses the same email accounts, and they work fine when I use straight dialup, I can't see it being something in Outlook. However, once I try to send attachments when connected via the DirecPC Navigator dialer, it won't send anything after that (not even straight text), until I exit Outlook, disconnect and reconnection using regular dial. Sometimes I even have to reboot. It's a mystery to me. Just wondering if anyone out there can shed some light.
