SBS 2008 Server becomming unresponsive and requiring power button to reboot weekly, need help

We have a client that has a fairly new HP ML series server (installed within 6 months new) that has Microsoft Small Business Server 2008 on it. They also have another physical HP ML series Terminal Server with Windows Server 2008 standard on it. Lately they have been calling weekly saying that they can not access anything (server shares, internet, etc) (fat or thin on the network). I can walk over to the console and SBS will not let me log in. I can try to log into the Terminal Server but it will tell me access denied. I cant access the SBS through logmein or the HP ILO port.

When this happens everything seems to stop (Athentication, email, dns). We have ran HP;s physical hardware test and everything checks out great. I have looked in the event log and whenever this happens there is a big gap until the server is rebooted under application and system. The only other errors I see are DCOM errors. We are at a total loss on this and any help is appreciated. I am trying to get assistance before having to call Microsoft.

Thanks in advance!

- Run SBS 2008 Best Practise Analyser tool and fix the errors reported.

- Does this server is being backed up using any backup application?

Cris HannaCommented:
My first recommendation
Are you running any anti-virus on the server?  Specifically Symantec Enpoint?  Remove it from the server..temporarily.
Have you disabled IPv6?

Visualize your virtual and backup environments

Create well-organized and polished visualizations of your virtual and backup environments when planning VMware vSphere, Microsoft Hyper-V or Veeam deployments. It helps you to gain better visibility and valuable business insights.

Currently we are running Sonicwall Enforced Antivirus Protection (Mcafee). IPV6 is not disabled. I will try running the best practices tool and go from there. I dont recall there being any BSOD though. It is weird when the server quits responding it does not lock up, it just loses all network communication and if you log into it the wheel keeps spinning and will not let you in. Its not like a hard freeze.

If you have not already done so, I would install SBS 2008 Update Rollup 4

While some may certainly disagree, I have found significant issues with SBS 2008 and automatic updates. I have disabled automatic updating on several of the SBS 08 I control, and just manually install them every few weeks.

Cris HannaCommented:
Jerry, not clear what you mean by automatic updates.   If you're using SBS 2008, there should be no automatic updating of anything.   There are certain categories which are automatic approvals but they don't get installed until someone manually installs them.  Any other configuration would be outside best practice

I completely overlooked the fact that the HP iLO port was in shared mode essentially making it a second network adaptor. Also found an issue with IPV6 in "Fix my network" tool. IPV6 wasnt disabled but had an issue with DHCP that was fixed. Thanks for all your help!
