Nettalk Duo Won’t Configure Behind Multiple Network Switches/Hubs

Posted by Russell Wright on March 13, 2011

I recently moved my Nettalk Duo from my office to my home and found that it wouldn’t get an IP address or configure itself in my home office.  I have multiple switches/hubs…in fact, the device I was plugging the Nettalk Duo in to is actually an old Linksys EFAH05W network hub.  The hub is uplinked to another switch in my wiring closet.  When I plugged the Nettalk Duo into the Linksys hub, it would never configure itself.

However, after I unplugged the uplink cable and plugged it directly in to the Duo, DHCP did its wonders and the Duo was configured and operational.  Afterwards, I found that I could plug the uplink cable back into the hub and plug the Duo into an open port on the hub and it would continue to work.  Guess that old hub was kinda’ getting in the way.  Probably due for an upgrade.

Troubleshooting 0x800f081f Error on Windows 2008 R2 SP1 Installation

Posted by Russell Wright on March 9, 2011

I have two servers that are nearly identical running Windows 2008 R2.  Both are Hyper-V hosts.  While attempting to install Windows 2008 R2 SP1 on my second server, I ran into the following error.  I attempted the installation from both Windows Update and the standalone downloaded SP.

My original thread on this problem is posted here.

I found posts that refer to the Remote Server Administration Tools (RSAT) but since this was NOT Windows 7 and I had not installed the RSAT tools, I was at a loss.

I also found this thread that seemed to be similar to my issue, except the O/S was Windows 7 instead of Windows 2008 R2.


I installed the System Update Readiness Tool with no change in the outcome.

I also attempted a system scan using sfc /scannow which found errors, but did not correct the problem.  The CBS.log had several errors listed, but nothing that led to a quick solution.


Many thanks to Andreas_L for pointing out the error in the System Event Log that led to a fix to my problem.


Using the Deployment Image Services and Management Tool as suggested, I ran a /remove-package command for the offending package identified in the System Event Log.  I was able to copy/paste the package name from the error.

dism /online /remove-package /packagename:Package_for_KB976932~31bf3856ad364e35~amd64~~


Something weird happened to my RAID 1 volume when this was run (3ware 9550sx controller) but it didn’t stop me from installing the SP.  After I rebooted, the RAID rebuilt and is running fine.


It finally took off!


And completed without issues.

Service Pack 1 complete
