Microsoft has finally made some improvements to the DHCP server role with its introduction of Windows Server 2012. One of the most exciting changes being the ability to make your DHCP servers highly available!
However, upon our testing of this new feature, we found that it does not like DHCP reservations and would cause our reserved IP’s to be listed as BAD_ADDRESS in the scope. This of course prevented those PC’s from obtaining an IP address, rendering them virtually useless! This issue exists in both Load Balanced and Hot Standby modes.
I just finished implementing the new Windows Deduplication on some of my backup volumes and decided to share the results. I’m pretty impressed with the numbers. Its pretty easy to set up, just install the Role Service, then right click a volume in server manager to turn it on. It creates scheduled tasks that you can adjust.
So I went to remove a program from startup today on a Server 2012 machine and typed in msconfig like I always have and received this error “Startup items are not enabled on this system.” In Windows 8 you can use task manager but not true with 2012. my googling has been unsuccessful so far. I know you can use a third party tool or edit the registry directly.
You can also check these folders: %appdata%\Microsoft\Windows\Start Menu\Programs\Startup and folder %ProgramData%Microsoft\Windows\Start Menu\Programs\StartUp
Here is the sysinternals tool.
I’ll post back if I find a better solution. “not enabled” leads me to believe you can enable it…
According to this MSDN Blog Post AppFabric is now supported on Server 2012. However I have been unable to create a clustered cache on the standard edition of 2012. I found the following in the event log:
“The High Availability feature of AppFabric Server caching features requires all nodes in the cache cluster to be running Windows Server Enterprise Edition or higher”
That makes perfect sense for Server 2008r2 considering you can’t do any clustering without Enterprise edition, however things have changed with server 2012. According to Microsoft:
“Standard edition now offers all of the same enterprise-class features as Datacenter and is differentiated only by virtualization rights.”
I have commented on the MSDN blog without luck…
Microsoft has finally released a patch to address this issue. The patch can be found here: http://support.microsoft.com/kb/2800726
