Network Connection Settings Don't Match Registry

i asked check nic settings on 6 nodes in our exchange 2007 mailbox cluster after 1 of active nodes stopped communicating others.  servers windows 2003 x64 sp2 on identical hardware.  checked confirm drivers same on 12 broadcom nics , newest drivers.  confirmed kb948496 update was installed.  confirmed in registry enabletcpchimney, enablerss , enabletcpa set 0, yet in settings each network adapter, receive side scaling , tcp/ip offload show enabled.

according article, can use above registry settings disable above network adapter settings.  can tell me if need disable these settings on network adapters, or can assume settings ignored because of registry settings?

hi chasboston,

 

thanks posting here.

 

if can confirm these registry keys had been set disabled , think these features disabled adapters well.

to figure out root cause of issue , narrow down more effectually , discuss cluster system and  this connectivity issue in detail ?

have modified system settings server ?

 

you may check if works reset , reconfigure network settings on server first. may start troubleshooting issue following kb325487:
