Same with my server. I'm guessing that for it to function it has to be enabled both in the OS and on the NIC. But how can you verify that?

This was not an upgraded server, it was a bare bones fdisk.

I just checked my OS and it's off by default: C:\Users\admin>netsh int tcp show global Querying active state...

That one hit my DC's hard on 2003. Or maybe it actually works in 2008. Checking now...I'll be danged, it is enabled by default and not blowing up. From: Miller Bonnie L. [mailto:[email protected]] Sent: Friday, January 09, 2009 2:30 PM To: NT System Admin Issues Subject: Server 2008 and TCP Chimney Anyone know if the TCP Chimney/RSS/etc issues that affected WS03 with SP2 or the SNP on SP1 are a problem on Server 2008? This talks about changing it, but not what the default status is: http://support.microsoft.com/kb/951037 I have a few WS08 servers, but am just now installing the first one that might be affected by this issue (Dell 2950). Wasn't sure if this is off by default in '08, is not an issue, or what, and I'm not to the point yet to be able to look at it.
