Event ID 118 — Remote Desktop IP Virtualization Availability

Applies To: Windows Server 2008 R2

Remote Desktop IP Virtualization relies on the proper network adapters to be enabled on the RD Session Host server.

Event Details

Resolve

Ensure that the network adapter is enabled, or free up memory

To resolve this issue, identify and fix any issues with the RD Session Host server by doing the following:

• Ensure that the network adapter used for Remote Desktop IP Virtualization is enabled.
• Free up  memory on the RD Session Host server.

To perform these tasks, refer to the following sections.

To perform these procedures, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

Ensure that the network adapter used for Remote Desktop IP Virtualization is enabled

The network adapter used for Remote Desktop IP Virtualization must be enabled for Remote Desktop IP Virtualization to work correctly.

To ensure that the network adpater used for Remote Desktop IP Virtualization is enabled:

1. On the RD Session Host server, click Start, and then click Control Panel.
2. Click Network and Internet, and then click View network status and tasks.
3. Click Change adapter settings.
4. Right-click the network adapter to be enabled, and then click Status. 
5. Ensure that the Media State status is Enabled.

Free up memory on the RD Session Host server

One way to increase the amount of available memory is to determine if there are any programs or processes running on the RD Session Host server that can be closed. Use Task Manager to determine which processes are using the most memory, and to end those processes.

To free up memory on the RD Session Host server:

1. On the RD Session Host server, right-click an empty area of the taskbar, and then click Start Task Manager.
2. Click the Processes tab.
3. Make sure that the User Name and Memory (Private Working Set) columns appear. If they do not appear, on the View menu, click Select Columns, select the User Name and the Memory (Private Working Set) check boxes, and then click OK.
4. At the bottom of the tab, select the Show processes from all users check box.
5. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
6. To sort the processes by memory usage, click the Memory (Private Working Set) column header.
7. Determine if you can end any of the memory-intensive processes.
8. To end a process, click the process name, and then click End Process.
9. Click End Process to confirm that you want to end the process.

If you cannot free memory by using Task Manager, or if this issue still occurs after you try to free up memory, restart the RD Session Host server.

Verify

To verify that an IP address has been assigned to a session or a specified program, you must use Event Viewer and confirm that Event 100 in the Microsoft-Windows-TerminalServices-TSAppSrv-TSVIP event source was written to the System event log.

To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.

To confirm that Event 100 was written to the System event log:

1. On the RD Session Host server, open Event Viewer. To open Event Viewer, click Start, point to Administrative Tools, and then click Event Viewer.
2. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes.
3. In the left pane, expand Windows Logs, and then click System.
4. Look for an event with a Source of Microsoft-Windows-TerminalServices-TSAppSrv-TSVIP and an Event ID of 100. This event indicates that Remote Desktop IP Virtualization started correctly.
