Server 08 64bit - Slow Outlook Performance

Multiple Server 08 machines with Outlook 07 show the same problem...extreme latency to the exchange server. It takes up to 30-45 seconds to open an email of only 50kb. I've created my own virtual test environment and duplicated the reports.  This is only on Server 08 x64 machines. Everything works perfectly on all other OS's. Process explorer shows nothing out of the ordinary. CPU load is minimal and there's no other tasks or processes running that would slow things down.

I had the networking team look at the situation and the connection is just fine to the machine and to the exchange server. Ping test are just fine.

Previously performed troubleshooting:

 - Moved exchange data stores to different exchange servers (03 & 07)
 - Disabled Anti-virus
 - Updated Office with the most up to date updates and patches.
 - Checked AD group policies for issues.
 - Checked processes and server load.

Has anyone experienced anything similar to this? Microsoft phone support has been less than helpful.

Remove the AV totally for testing.

Disable Large send offload, TCP Offload, IP Offload in your network card properties.

Disable TCP Chimney as well.

Thanks Dariusq...

I removed McAffe. I also did what you said regarding Offload and TCP Chimney. Unfortunately, I couldn't tell any noticable difference in the performance of outlook after reboot.

The following changes were made to the Network Adapter properties and via command line.

Here are the following properties under the network adapter on my VM test machine.
Interrupt Moderation - Enabled
IPv4 Checksum Offload - Disabled
IPv4 Giant TSO Offload - Disabled
IPv4 TSO Offload - Disabled
IPv6 TCP Segmentation Offload - Disabled
Jumbo Packet - Standard 1500
Large Rx Buffers - Not Present
MAC Address - Not Present
Offload IP Options - Disabled
Offload tagged traffic - Disabled
Offload TCP Options - Disabled
Proprity / VLAN tag - Priority & VLAN Enabled
RSS - Disabled
Rx Ring #1 Size - Not Present
Rz Ring #2 Size - Not Present
Small Rx Buffers - Not Present
Speed / Duplex - Auto Negotiation
TCP Checksum Offload (IPv4) - Disabled
TCP Checksum Offload (IPv6) - Disabled
TX Ring Size - Not Present
UDP Checksum Offload (IPv4) - Disabled
UDP Checksum Offload (IPv6) - Disabled
VLAN ID - Not Present

Have you removed the Team? Updated firmware and drivers?

No, I set up a test environment up because originally the problem was discovered on a production citrix server. I wanted to isolate all other variables from the situation so I created this VM running the same OS and installed Office. That's it.

This is affecting multiple servers.
The only thing they have in common is Windows Server 08 x64.

Disabling Autotuning did the trick!
Duplicated the fix on the virtual machine as well as the production server and the fix was immediate!

Thanks DariusQ. You just made my day!
Not only did this fix the problem, I'm getting my money back from Microsoft support since they didn't fix it!

Woo Hoo!
