Sonicwall TZ210w not responsive after SBS 2011 installation

About 30 minutes after we installed a new SBS 2011 box, our Sonicwall TZ210w went down. Not thinking anything of it, I just rebooted. About an hour later, same thing. It kept getting worse. They sent us a new Box. It's been running fine for about a week, and now the same thing.

We initially setup the TZ210w to be the DHCP server, but I switched it to SBS 2011 hoping to fix. I also updated the firmware on the TZ. Just so you know, the TZ is NOT uPNP.

Anyone have any ideas what would make an SBS box shut down a firewall? I think it's a HUGE coincidence that it happened right after the new server.

Any thoughts or leads would be appreciated. I am going to turn on Syslog and see if I can find anything today.

Is it a brand new server? Is the Server plugged into a switch or directly into the Firewall?

New Hardware migrated from SBS 2003 via swing migration. Server is plugged into switch, which is plugged into Firewall

Are you certain the Sonicwall is "shutting down" and not an SBS service?
Other than UPnP, I can see no way the SBS can affect the Sonicwall.  However if DHCP is enabled on the Sonicwall, which it should not, the SBS will shut down its own DHCP service and client machines will be assigned incorect DNS information.

DHCP is SBS. We cannot even ping when it goes down, which is the IP Address of the Sonicwall.
Rob WilliamsCommented:
Can you post the results of IPconfig /all from the SBS?

>>"We cannot even ping when it goes down, which is the IP Address of the Sonicwall."
That doesn't necessarily indicate a problem with the sonicwall. I assume there is a reason you think the sonicwall is a problem??  Can the SBS ping other devices on the LAN?

Everyone maintains  a connection to the server, just the internet goes down.

Thanks, IP config saves asking a lot of questions like IPv6, DNS, and such.

To confirm, you can ping the Sonicwall for a while and access the Internet, but then both suddenly stop?
When this happens have you tried accesing a web site like Google using the IP ? If that works it is a DNS issue rather than routing issue, but if pinging of the server stops that is not likly the case.

Another thought is Sonicwalls have license limits.  For example if you have 10 licenses Internet works fine untill the 11th device (printer, PC, printer, guest) tries to access the Internet and then access is blocked.  

Again, other than license limits or UPnP, I can see no way the SBS is the source of the problem.

You cannot ping the sonicwall or outside when it goes down. You cannot get anywhere outside.

The sonicwall we have has unlimited licenses. We have the Pro firmware. Also, sonicwall does not do uPnP.

SBS might NOT be the problem, but it would be one of those HUGE coincidences. Like I said, it started happening 30 minutes after the new server. Also, the Sonicwall has been replaced with a new unit since. The old unit would not even do a hard reset to factory default.

We also have failover on the Sonicwall from 2 different ISP's, so I know it's not the ISP going down. Even if it did, 15 seconds later, the T1 goes live. The VOIP phones are on the T1 (Not connected to SW) and they work find when the internet goes down. Again, that is a backup line.

I am currently running Syslog, so I will hopefully get something out of that.

It's been working fine for a week on the replacement TZ. Any other ideas?
Rob WilliamsCommented:
I can't think of anything else.  You mentioned; "The old unit would not even do a hard reset to factory default"  which is a definate problem with the Sonicwall that the SBS cound not possibly cause. It is very odd though.  I aam hoping others will have some suggestions.

Is the replacement working? You had stated both:
"It's been running fine for about a week, and now the same thing."
"It's been working fine for a week on the replacement TZ."
AlskiAuthor Commented:
The old unit that we could not reset has been sent back to SW. We are currently using the replacement box.

At least I'm not the only one stumped!
