### Event ID 4038
Vmsal posted an error message to the user.
**Description**
An error message is displayed to the end user stating that MED-V could not start the virtual application.
**Solution**
If the error is logged two or more times in a row, stop MED-V and connect to the virtual machine by using Windows Virtual PC console and attempt to start the application in Full Screen.
### Event ID 4040

### Event ID 4043
Failed to reset expired password in the virtual machine.
**Description**
The end user did not reset the password in the virtual machine before it expired. As a result, the user might not be able to access network resources or save work.
**Solution**
Shut down the MED-V guest and restart it.
### URL Redirection
### Event ID 5005
Couldn’t get VM name from configuration; can’t launch guest browser.
**Description**
URL Redirection could not obtain the MED-V workspace name from the configuration. As a result, it cannot inform Windows Virtual PC to open the redirected URL in the MED-V workspace browser.
**Solution**
Ensure that the MED-V workspace name is set and that it matches a virtual machine name in the C:\\Users\\<*user*>\\Virtual Machines directory. The MED-V workspace name is located at HKLM\\SOFTWARE\\Microsoft\\Medv\\v2\\VM\\Name.
For example, if the user is "Matt" and the workspace name is "mattsworkspace", the value of HKLM\\SOFTWARE\\Microsoft\\Medv\\v2\\VM\\Name should be "mattsworkspace", and there should be a file that is named C:\\Users\\Matt\\Virtual Machines\\mattsworkspace.vcmx.
### Event ID 5006
Failed to create pipe server.
**Description**
The URL Redirection service could not create the pipe server to communicate with Internet Explorer.
**Solution**
Check system event logs for attempts to create a file or resource whose path begins similar to the following: "\\\\.\\pipe\\MEDVUrlRedirectionPipe\_" and ends with the user’s user name and domain name. If this is not present in the event log, restart the computer.
### ConfigMgr (Guest)
### Event ID 7001
The host network configuration data is not properly formatted.
**Description**
Either the network configuration received from the host is an incorrectly formatted XML string, or the network information returned from the host cannot be written to an XML document.
**Solution**
Restart the host computer and the virtual machine.
### Event ID 7005
A change to the host network configuration was detected, but was not able to be applied because the host network configuration data was not properly formatted.
**Description**
A change to the host network configuration was communicated to the virtual machine, but could not be processed in the virtual machine because of an error. This error could be caused by incorrectly formatted data or the inability to set the information into the Windows Management Instrumentation (WMI) CCMNetworkAdapter instance.
**Solution**
Restart the host and virtual machine.
### ConfigMgr (Host)
### Event ID 8006
The virtual machine cannot be found.
**Description**
Windows Virtual PC 7 cannot locate the virtual machine. The virtual machine might have been deleted, moved, removed, or access was denied.
**Solution**
Reinstall the virtual machine.
### Event ID 8008
The workstation's network configuration information could not be retrieved.
**Description**
Network configuration information could not be collected from the MED-V host, most likely because of a system call failure in the .NET Framework. This failure can also occur if the network information returned from the MED-V host cannot be written to an XML document.
**Solution**
Restart the host workstation.
### Event ID 8010
The network configuration data could not be set in the virtual machine.
**Description**
The MED-V host network address translation (NAT) could not be communicated to the virtual machine, most likely because the virtual machine is in a bad state or the Windows Virtual PC Additions were not installed or enabled.
**Solution**
Shut down and restart the virtual machine. In addition, you might have to reinstall the virtual machine.
### Event ID 8011
The network configuration data could not be reset in the virtual machine.
**Description**
The MED-V host network configuration (BRIDGED) could not be communicated to the virtual machine, most likely because the virtual machine is in a bad state or the Windows Virtual PC Additions were not installed or enabled.
**Solution**
Shut down and restart the virtual machine. In addition, you might have to reinstall the virtual machine.
### Printer Redirection
### Event ID 9001
File Permission Error.
**Description**
The end user is not authorized to access the folder required to open or create the MED-V printer file for reading.
**Solution**
Verify that the User\\AppData\\ path can be accessed and that the user has permission to read and write to it. For example, if the user is "Matt", the path C:\\Users\\Matt\\AppData\\, and all files therein should have Read and Write permissions. And if it exists, the path C:\\Users\\Matt\\AppData\\Local\\Microsoft\\MEDV\\v2\\ and all files therein should have Read and Write permissions.
### Event ID 9002
File Permission Error.
**Description**
The end user is not authorized to access the folder required to open or create the MED-V printer file for writing.
**Solution**
Ensure that the User\\AppData\\ path can be accessed, and that the user has permission to read and write to it. For example, if the user is "Matt", the path C:\\Users\\Matt\\AppData\\ and all files therein should have Read and Write permissions. And if it exists, the path C:\\Users\\Matt\\AppData\\Local\\Microsoft\\MEDV\\v2\\ and all files therein should have Read and Write permissions.
### Event ID 9004
Could not create path for storing MEDV printer files.
**Description**
The printer redirection service could not access files or create directories required for storing the printer information.
**Solution**
Verify that the User\\AppData\\ path can be accessed and that the user has permission to read and write to it. For example, if the user is "Matt", the path C:\\Users\\Matt\\AppData\\ and all files therein should have Read and Write permissions. And if it exists, the path C:\\Users\\Matt\\AppData\\Local\\Microsoft\\MEDV\\v2\\ and all files therein should have Read and Write permissions.
### Event ID 9005
Couldn’t get VM name from configuration; cannot launch guest installer. Cannot update MED-V – No host network detected.
**Description**
The printer redirection service was not able to obtain the MED-V workspace name from the MED-V configuration and cannot inform Windows Virtual PC to start the installer on the MED-V guest.
**Solution**
Ensure that the MED-V workspace name is set and that it matches a virtual machine name in the C:\\Users\\<*user*>\\Virtual Machines directory. The MED-V workspace name is located at HKLM\\SOFTWARE\\Microsoft\\Medv\\v2\\VM\\Name.
For example, if the user is "Matt" and the workspace name is "mattsworkspace", the value of HKLM\\SOFTWARE\\Microsoft\\Medv\\v2\\VM\\Name should be "mattsworkspace" and there should be a file that is named C:\\Users\\Matt\\Virtual Machines\\mattsworkspace.vcmx.
### Application Publishing
### Event ID 10015
A file system error occurred during the reconcile process. The reconcile process will not process the file <*filename*> but will continue to process any other changes.

**Solution**
Ensure that the command is executed with the following format:
Medvhost.exe /GuestWakeup /d:< *duration\_in\_minutes*> /v:”< *workspace\_name*>” where
<*duration\_in\_minutes*> is the number of minutes that the virtual machine should stay awake (default is 240) and
<*workspace\_name*> is the name of the virtual machine that should be awakened.
### Event ID 11002
Cannot update MED-V – No host network detected.
**Description**
Guest patching could not finish because no host network connection was detected.
**Solution**
Connect the MED-V host to an active network connection before you run guest patching.
### Event ID 11003
Cannot update MED-V – Host not running on A/C powerFailed to create pipe server.
**Description**
Guest patching could not finish because the host appears to be running on battery power instead of from a power cord.
**Solution**
Connect the host computer to a power cord before you run guest patching.
### Client UX
### Event ID 14003
The following tray status message was too long and could not be displayed: <*tray\_status\_message*>
**Description**
