Dealing with Windows Terminal Services licensing issues

Brian gives a nice overview of Microsoft Server 2008 licensing. I’ll post it here for quick reference because God knows I need it.
Thanks Brian.
Dealing with Windows Terminal Services licensing issues.

There are multiple license requirements for Windows Terminal Services (TS). These requirements vary depending on how TS is used and what version of Windows it is being used on (This article deals with Windows Server 2008).
Available license types
Five types of licenses are available for Terminal Services in Windows Server 2008:

License Function
Windows Server License Every Windows 2008 server requires a Windows Server License. This license allows TS to be used.
Windows Server Client Access License Any computer connecting to a Windows server requires a Client Access License (CAL). Although the basic CAL does not cover TS use, it is still required for general connectivity to the Terminal Server.
TS Device CAL In addition to the CAL, computers connecting to TS require an incremental CAL that is specific to Terminal Services. One option is to use a TS Device CAL. This CAL licenses any device to connect to Terminal Services, regardless of how many users actually use that device.
TS User CAL An alternative to the TS Device CAL is the TS User CAL. This CAL allows one user to connect to Terminal Services from any device.
TS External Connector The TS External Connector license allows external users to connect to Terminal Services. This is a server-level license, and you will have to license each Terminal Server if you provide external connectivity.
Service Provider License The Service Provider License is intended for service providers that offer hosted services to their customers.

Typically, the most cost-effective way to license TS is either TS User CALs or TS Device CALs. Alternatively, you can use a combination of TS User and TS Device CALs should the need arise.



Disconnecting hard drive on Fresco Logic USB 3.0 (Win7x64) on ASUS U36JC

On my ASUS U36Jc-B2B laptop, I’ve been trying to copy large files (>3GB) to my (work’s) Western Digital Passport 3.0 750GB USB drive. However, this always resulted in the drive disconnecting and the copy operation failing. I’ve tried numerous driver uninstall and reinstall with the same result, until I found a post linking to this driver.
This is the version. The latest posted version of this driver on ASUS’s website was
Nonetheless, I can now copy files without the drive disconnecting.
I’m not sure the throughput is 100% as I’ve seen the same drive hit upto 92MB/s on my Intel desktop machine.
Hope this helps anyone out there with similar issues.

Improper shutdown of DFSR server, internal database error and restore files from "ConflictAndDeleted" or "PreExisting" folders

While trying to debug PowerChute Network Shutdown 3.0 on ESXi5, an improper shutdown of the DFSR server resulted in the following:

Source : DFSR
Catagory : None
Event ID : 2104
Type: Error
Description :
The DFS Replication service failed to recover from an internal database error on volume F:. Replication has been stopped for all replicated folders on this volume.
Additional Information: Error: 9203 (The database is corrupt (-1018)) Volume: DB587759-DC0B-11DC-940D-00304888DB13 Database: F:System Volume InformationDFSR

Steps to resolve:

  1. Stop the “DFS Replication” service.
  2. On the drive(s) in question, grant yourself full permission to the hidden system “System Volume Information” folder.
  3. Navigate to each replication group the server was a member of and delete (or move to be extra careful) each hidden system “DfsrPrivate” folder.
  4. Start the “DFS Replication” service.

You may now treat the server as a brand new member for the replication groups. Now all you need to deal with is DFSR’s sloppy initial replication routines (hint: those missing files are in the “DfsrPrivate PreExisting” folder).
However this did not work the folder would not rename under 2008 even with UAC off, this did work for me though

  1. Click Start, right click Command prompt and click run as administrator to open a command prompt window, then go to driverletter:System Volume Informationdfsr prompt
  2. Type “ren “old folder name” “new folder name””

Use this simple vbscript to allow recovery of DFS Replicated files that have been pushed into the ConflictAndDeleted or PreExisting folders due to misadventure.
You might also find the %systemVolume%windowsdebug folder useful.
