ISP: AT&T, Netopia

When the MS updates came down last night one of them needed a reboot of the server. When the server rebooted, the static IP address (10.1.10.2) was somehow in use by some other device. Therefore since it couldn’t assigned its own IP address (static) the DNS service would not start. Since DNS would not start, clients on the network relying on that couldn’t get out to the web. Since it didn’t have an IP address, the server itself could not gain access to the network (internal and external).

What it seems to be is that the Sonic Wall is taking that IP address. How, you ask? Don’t know. When I assign 10.1.10.2 to the server, unplug the Sonic Wall and reboot the server, there are no IP conflicts. I plug Sonic Wall back in and wala! Back on the Internet, everything is fine. However, when I reboot the server with Sonic Wall online, it loses its IP address and complains that 10.1.10.2 is already assigned.

Temporary solution is that I have set Automatic Updates to be downloaded and not installed automatically, giving us the opportunity to reboot if need be using the process above. They have also asked for a quote for a different VPN firewall be put in place. This is also because we are still unable to get Nader up-and-running on the SonicWall VPN whereas other clients are not having any trouble.

DHCP is off on the sonic wall and is on the Windows Server. Both have ranges, but neither include 10.1.10.2 within their range.

What more information can I provide to get this resolved?]]> http://www.dslreports.com/forum/Windows-Server-losing-Static-IP-22788156 Thu, 30 Jul 2009 09:12:04 EDT
