Extended error has occurred

Problem

You can see the error message "Extended error has occurred" on the screen when you try to do either of the following:

  • During image creation, while accessing a image repository
  • During deployment, while accessing the image repository

 Cause

  1. Error while accessing the network share using it's UNC path.

  2. Credentials to access Image repository has expired. 

  3. The source machine has stored credentials pertaining to the target share, and those credentials are obsolete.

Resolution

To resolve this problem, follow the steps given below:

Try using IP Address based share path instead of UNC path

To resolve this error during image creation, 

  1. Create a new image repository using an IP address instead of DNS name following the steps given below. 
  2. Go to Desktop Central Server -> OSDeployment -> Image Repository -> Add Image Repository
  3. Add repository as \\IPAddress\sharedFolder. For eg: \\192.168.10.20\osdImages

After adding the image repository, try image creation using this newly added repository.

To resolve this error during deployment, 

Create a new image repository using IP address instead of DNS name following the steps given below. Then modify the image repository path from the old one to the newly added repository path. To get this done follow the steps given below,

  1. Go to Desktop Central Server -> OSDeployment -> Image Repository -> Add Image Repository
  2. Add the new repository as \\IPAddress\sharedFolder. For eg: \\192.168.10.20\osdImages. The new repository will get added now.
  3. To modify the repository path, go to Desktop Central Server -> OSDeployment -> Create Image
  4. Click on the specific image which you are going to deploy.  Now you will be redirected to the info view of the image.
  5. There will be a "Image repository" edit option. Click on it and modify the repository name into newly added one and then try deployment.

Logout image repository machine & login again with the new credentials

  1. Go to the Image Repository machine 
  2. Logout & create new password if expired and login with the new credentials.
  3. Now, update new password for the particular user in Desktop Central Credential manager by navigating to Desktop Central -> Admin -> Credential Manager -> Edit Credential 

You can now retry image creation or deployment.

Remove the obsolete/expired credentials stored in the system cache. 

  1. Go to the machine where you are trying image creation. Click Control Panel -> Credential Manager.
  2. In the Windows Credentials and Generic Credentials section, remove the stored credentials which are leading to issues.
  3. Click Details --> Remove --> Yes on the warning box.
  4. Repeat the above steps if you want to remove more than one credential.
  5. Close the Control Panel window.

You can now retry image creation. 

Delete the old network share connections

  1. Go to the machine where you are trying image creation. Click Start button, right-click command prompt then select Run as administrator.
  2. Type net use and press Enter.
  3. You can view the list of mapped drives. In many cases, the drive may not be assigned to a drive letter, look for such drives in the list and remove them. 
  4. To remove the drive, open command prompt, type net use /delete \\servername\foldername and press enter. Here the \\servername\foldername is the drive that you want to delete.

Note: In some cases, you may want to delete all the mapped drives, in this case use command net use * /delete. This will delete all mapped drives.
