DFSR on windows 2003 R2 servers.

1. Start DFS management console on any Windows 2003 R2 server.
2. Configure Replication (membership, connections and replicated folders). If you already have a previously shared folder what you want to replicate on other server - do not copy files, just replicate.
3. After the replication is done configure a namespace.
4. Publish the replicated folders to the namespace, and configure login script to access the published share.

Windows 2008 Terminal services

To configure access:

1. Create AD group, for example: "TS Users"
2. Put the group in local "Remote Desktop Users" group on the terminal server.
3. Put the terminal server in local "Terminal Server Computers" group on the "TS licensing" server to enable to read licensing information.
4. Put the terminal server in separate OU and create a GPO. The GPO "Security Filtering" should include the terminal server itself and "TS Users" group. This will disable all limitation for administrators. Do not include administrators in "TS Users". Remove "All Authenticated" group from the GPO "Security Filtering"

Hyper-V Config 4096 Error

In my case it was old references to removed VMs on my Hyper-V host: 

"The Virtual Machines configuration DC6D0B26-9438-4504-9500-73342A42EC0B at 'E:\UTIL02-VM' is no longer accessible: The system cannot find the path specified. (0x80070003)"

So, I just delete configuration reference XML file  "DC6D0B26-9438-4504-9500-73342A42EC0B.xml" from: 

"C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines"

But be careful, do not delete valid reference!

SLMGR - license manager

I took the reference from other blog - slmgr tool is "Software Licence Manager" :"SLMgr Commands and Options

I’ve been dealing a lot lately with activation of Server 2008. It’s not been as easy as I’d like. In searching for some help, I came across a great article on SLMgr: SLMgr Commands and Options with Windows Vista Product Key Activation. This article provides a good look at the options with this SLMgr.ext tool.
