With all due respect to Rick, I DID try the latest Intel drivers from Microsoft, then Dell, then the Intel site. No difference. I also flashed the server's bios, ESM, Raid, etc. EVERYTHING was up to date. And I had the problem with IMail only. The server being a DC and file server performed with great speed. Only IMail showed problems. And it showed those problems if I was sitting at the server console logging into webmail using the server's IP address. I would think that should rule out any network card-related issues. *AND* after disabling the Intel NIC (admittedly only in Windows) and putting in a 3com NIC, I *STILL* had the problems.
Dev may have found a way for us to get around whatever shortcomings there are in IMail's software. But we certainly can't be expected to spend countless hours of finding tweaks and fixes to get around someone elses problematic software. And even if that WAS the solution, it should come from IpSwitch. Their answer should not be to change hardware when evidence is becoming more clear that the problem is not the hardware. We run all Dell hardware with Intel NICs. And we run some very specialized applications on them. None of them exhibit any performance problems (or ever have). So I have a very hard time believing that this NIC is to blame. --Todd. ----- Original Message ----- From: "Rick Leske" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, December 13, 2002 9:25 PM Subject: Re: [IMail Forum] FIXED!
