DL380 G4 network connection problem


I have Proliant DL 380 G4 with Broadcom NIC, with OS Windows 2003 Server SP2 on it, and the latest support pack installed. We have unsolved problem for more than a year which is sometimes network connection suddenly dropped with no error logs on event viewer. It was begun when I applied SP2 on it. I have read about TCP offload issue on W 2003 SP2, and already implement the workaround from MS sites by turning off RSS and TCP Chimney, but still the problem persisted. Once the problem corrected when I install the latest support pack, but now when there is critical patch issued by Microsoft, and I installed the patch, the problem re appeared. Is anyone has same problem with me and managed to solve this?

Re: DL380 G4 network connection problem

We had relatively the same issue ( DL385 G2 servers ). Below are the steps that we followed to solve it:

Issue: HP Proliant DL385 G2 servers intermittently goes out off the network and hangs
at applying personal settings.


1: NIC card & teaming driver.

2: The TCP/IP Offload-enabled network adapter may consume lots of nonpaged pool memory. This may cause other problems in the operating system.

3: In some cases, the TCP/IP Offload-enabled network adapter may request large blocks of contiguous memory. This makes the computer stop responding when it tries to free the memory.


1) Uninstall the NIC cards from device manager and re-install it again.
2) Update the NIC card driver, NCU, Teaming driver and ILO.
3) Dis-solve teaming and reteam the NIC.
4) If nothing works, enable the server with single NIC.

Solution: Try the solution one by one. If solution 1 fixes the issue, do not try the other solutions.

Solution 1: Upgrade the tcpip and netbt drivers for Windows 2003 SP2 to their latest revision available in the following rollup package:

A Scalable Networking Pack (SNP) hotfix rollup package is available for Windows Server 2003 -

Solution 2: Disable the TCP Chimney offload feature from the following link:

Along with this get network card driver and firmware updated to latest as mentioned in following HP site:- &prodTypeId=15351&prodSeriesId=3219233&swLang=8&ta skId=135&swEnvOID=1005#12212

Solution 3:
After you install Windows Server 2003 Service Pack 2 (SP2) or Windows Server 2003 Scalable Networking Pack (SNP) on a computer that has a TCP/IP Offload-enabled network adapter, you may experience many network-related problems.
The following issues may occur when Windows Server 2003 SNP is turned on:
a.You experience intermittent RPC communications failures.
b. The server stops responding.
c. The server runs low on nonpaged pool memory
This update turns off default SNP features.

Re: DL380 G4 network connection problem

Thanks for your clues, I've already try your instructions on my server, but the result is still the same. Is there any other solutions that I can follow?
