Error: “A Device Attached to the System is Not Functioning” While Reconnecting To Previous Session

Solution 1

KB2661332

Csrss.exe has a deadlock with Microsoft Excel or Microsoft Visio

Solution 2

KB2383928

The issue occurs because of a problem in the Win32k.sys driver.

If a remote desktop session exits before the session is completely initialized, the state change notification of the session is not sent to the third-party driver. In this situation, the driver can leak resources, such as a system thread, in the context of Csrss.exe because the third-party driver cannot unload. The leaked thread causes the remote desktop session not to exit completely. After the computer is running in this status for some time, the Local Session Manager (Lsm.exe) blocks new incoming connections. Additionally, these orphaned sessions also cause the shutdown process to stop responding. Therefore, you experience the issue that is described in the “Symptoms” section.

SEPM affecting domain joining from remote system

I need a solution

I have a AD DC running SEP 14 which has several computers successfully domain joined.

I am trying to domain join another system which connects through a VPN, but this is not working.  I have double checked that all protocols are allowed through the VPN, and am now fairly sure it’s SEP blocking it.  2 questions:

– Does SEP somehow distinguish a local computer from a remote one?  The remote system in my case is picking up a local IP address.

– What do I need to open up to allow a remote computer to join the domain?

Connectivity issues with the HDX RealTime Optimization Pack 2.7 while connecting Skype for Business

This issue is applicable only for Skype for Business users with HDX RealTime Optimization Pack version 2.7 on hosted shared desktops. That is, a published desktop running on a remote desktop server or Skype for Business published as an application on Citrix Virtual Apps server.

When Skype for Business is running, the user might see that the RealTime Connector connection on the notification area (“bow tie”) disconnects and reconnects randomly.

If you are on a Skype for Business call, the active call might drop due to this behavior. This issue doesn’t occur if the user is on dedicated hosted VDI (Citrix Virtual Desktop). With a dedicated hosted VDI, each user receives a virtual desktop rather than multiple users sharing the single server as with RDS (Citrix Virtual Apps).
