Problems with MS Windows 2003 server SP2

[TT28]

I am operating Proliant ML350 G5 server with 3 network adapters (LAN, WAN, ILO2) and MS SBS server (Windows 2003, SQL, ISA, Exchange). Update services are trying to install service pack 2 with following errors: ID 4373 - Windows 2003 SP 2 instalation failed and ID 20 - service pack 2 instalation unsuccessfull because of error 0x800705b3. In such casa I have installed SP 2 directly without any problem. Logs - OK, Health monitor - OK, but it is not possible to connect the server from other LAN computers - Internet, Domain login, Exchnage does not working. I can see the server on network places or connect server shared folders. Can anybody advice, where could be problem ?

I think I had the same problem with a pair of new DL580s. You might try disabling a Windows network setting called Receive Side Scaling as described in this KB article:

The main symptom of the problem is that you can't make inbound or outbound TCP connections, while other traffic, such as ICMP or UDP, works fine.

It seems to only affect systems with SP2 and new NICs with iSCSI or TOE features.

Hope it helps.

Dear Chris,
I am very sorry for so late reply, but I used to use Service Pack 1 because of problem mentioned above. I have done windows registry change according to your advise (Enable RSS - 0). It was helped me very much but probleh has not been solved for 100%. I have changed one more parameter (EnableTCPA - 0) and server is working without troubles. In case, thank you very much for your help, I have drink for you :-)

Here is the solution:
1. Instalation of service pack 2
2. Change parameter in windows registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
EnableRSS to 0
EnableTCPA to 0
3. Restart the server
