Are we talking about the Rx and Tx TCP and IP checksum offloading? That's the only offloading I can see in the properties for my Gig adapter on my HP server...

Same issues we have. You can disable RSS, which seems to help the most but disable Chimney seems to do the trick across the board. -----Original Message----- From: Matt Bullock [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 29, 2008 1:34 AM To: NT System Admin Issues Subject: RE: IP Chimneys Can I ask what RDP issues? I got 5 new Dell 1950's with Dual Broadcom NIC's, and an add-on Intel NIC for the SAN. I was thinking about using the Intel for the regular network, and the Bcom's for the SAN, so I moved the network settings to the Intel, and RDP was barely usable, and network speed was crawling. I didn't have time to spend troubleshooting it, so I moved everything back to the Bcom'. No problems since.

No Broadcom cards though. I now disable it immediately after an SP install. -----Original Message----- From: Michael B.

What I've seen is ephemeral port exhaustion, general networking errors, ICMP failures (i.e., pings no longer work), etc. I've not heard of any "corrupted attachments". The way Exchange transfer files should prevent that. Regardless, just disable it. It doesn't have any negative impact to do so. Regards, Michael B.

I've done a quick google, and it appears people are blaming everything from sore feet to un-contactable servers on the TOE stuff. Other than the hanging during a reboot, what else is meant to be happening ? Olly -----Original Message----- From: Michael B.

We are seeing some corruption of attachments at a clients and there are reports that disabling this feature may have an impact. Anyone seen any issues so far?
