2012 Remote Desktop KVP Sessions


  • Hi

    With our new 2012 RD Server, I have 10 CALS installed (per user).  Say if the 12 users log in, I notice in the event log two errors with the same event ID.  The sessions seems to work fine for everyone connected.

    1152 TerminalServices-RemoteConnectionManager
    Failed to create KVP Sessions String.  Error Code 0x8007007A

    Do I need more CALS?

  • Hi,

    Generally, users will be disconnected when Event ID 1152 occurs. Based on my research, it would be related to licensing. However, I suggest you use Remote Desktop Licensing Manager tool to confirm the licensing issue.

    Meanwhile, I recommand you purchase more CALs for your additional two users.

  • I have the same problem, and I've verified that I don't have any licensing issues with our Terminal Services Licensing Server... What else could this be?

    I use remoteapp on a Hyper-V machine that serves about 20 users. Some of them are reporting random disconnects (not all of them), and this is the only error I see in Event Viewer (Failed to Create KVP Session Strings)

    Any ideas?

  • Did you ever come up with a solution to this issue? same issue, not all users report disconnects. checking every event viewer log, only problem child is the 1152 event.
