Dave, Check your SQL server configuration. SQL server defaults "automatic" mode and them enables SQL to use 100% of both memory and processor resources. When installed on a server that's not a DEDICATED SQL machine, it's wise to back off both the memory and processor resources available to SQL to a max of 50% of both. Depending on the memory you have installed on the new machine, you might also want to back it down ever further.
Remember, too, that both SQL 2005 and Windows Server 2003 require significantly more memory than previous versions of either required. Good luck in resolving this.

Are you referring to mail delivery loop times, send, receive, general speed issues, etc? Do the actual Imail logs reveal anything of interest? In older versions, we'd see 'stack connect failures' related to slow delivery times. Not sure what you may see on recent versions. 2 The 'Windows cannot obtain the domain controller name' error is likely due to the fact that you are not using an AD enabled DNS. If your server is joined to a domain and trying to AD authenticate for any reason(specifically, SQL permission queries to the DC), and if your websites and the Imail app are trying to use SQL for any reason, this could cause significant speed\lookup issues. Also, there is a documented issue with Imail\2003\DNS, but I seem to think it is was function and not performance related. 3 What are your Performance Monitor stats? Any disk, proc or memory saturation occurring? 4 Any real-time AV running on your box, perhaps scanning more than it should? I'd first try utilizing your own DNS. DNS is highly critical to mail delivery performance and should not be done remotely.

The old and new server are both running 8.21. The old server was running SQL Server 2000, the new one has SQL Server 2005. Old server was running Windows 2000 Server, new one has 2003 Server Small Business. The old one had its own local DNS server setup, but the new one does not have it yet, so we're using Covad's DNS servers and when pinging them, they seem fine (little latency). I contacted Covad and they say our network traffic is no where near peak so we should be fine there. They both are using Declude 1.81, sniffer, f-prot and WorkgroupShare (not Imail's version) for Outlook sharing. It also appears as though the few websites we are hosting on the same server are also much slower. The new server has a much faster processor and 4gb of RAM, so I'm thinking it's not the hardware (could be the NIC). Could it be IIS or SQL Server? If it were just the mail delivery, I would think Imail, SQL Server or the NIC card. But since the web sites are also slower, does that mean Imail is not the problem (so I'm left with it being SQL Server, NIC, or IIS)? One error I get in the Event Viewer is this: Windows cannot obtain the domain controller name for your computer network. (An unexpected network error occurred. ). Group Policy processing aborted. and this: Error: The Template Persistent Cache initialization failed for Application Pool 'DefaultAppPool' because of the following error: Could not create a Disk Cache Sub-directory for the Application Pool. The data may have additional error codes..
