Repair or recreate a corrupt repository GlobalManifest.metadata file in Quest vRanger – There is an error in XML document (x, x).

August 16, 2012 Leave a comment

I recently got the following error message from some of my backup jobs in Quest vRanger after one of my CIFs data repositories became out of sync with vRanger. The error I was getting was:

An internal error occurred during execution, please contact Vizioncore support if the error persists. Error Message: There is an error in XML document (1, 1).

I had a stack of backups in this repository and didn’t really want to try and edit the file manually. Renaming the corrupt GlobalManifest.metadata and running one of the backup jobs again created a new GlobalManifest.metadata file but this didn’t include any of the existing savepoints so I looked for another solution.

In the end I found this KB Article, that referenced this post explaining how to use the reposync02.ps1 powershell script to scan and recreate the GlobalManifest.metadata file for the repository. Its a great script. You may need to install Powershell 2 if you are running vranger on an older OS. The Windows 2003 version of Powershell 2 can be found here

Windows 7 SP1 installation fails with error 0x800f0818

August 7, 2012 5 Comments

I came across a peculiar problem today trying to install SP1 on a Windows 7 laptop. Whenever I ran the Windows 7 SP1 installer or tried to update to SP1 using Windows Update the installation failed with a cryptic error ‘0x800f0818‘. I tried various things such as running sfc /scannow and installing the Windows 7 System Readiness Tool (64 bit in my case), but neither reported problems.

After a bit of digging I found an entry in the CheckSUR log file found in C:\Windows\Logs\CBS which seemed to be related. In this case a .Net Framework update had failed to install a few times and this particular update was referenced in the log file:

To fix the problem I had to remove entries for the corrupt package from the registry (IMPORTANT: taking a backup first) from:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages

The specific entries are shown below. There are two, the highlighted entry, and the one beneath:

Deleting corrupt package entries from the registry

 

After deleting the two entries I reran Windows Update checking for updates and this package was redownloaded and then installed without issue. After this the service pack 1 installation proceeded without error. You may find that the specific update referenced in your CheckSUR log is different to the one mentioned here, but the method is the same.

Allow popups from certain websites using a group policy object

If you need to allow pop ups from specific websites when using Internet Explorer in your environment, you can enable them by using the ‘Pop-up allow list’ setting in the relevant group policy object (GPO).

Simply edit the relevant GPO, adding the addresses of web sites that you wish to allow pop ups for. The setting can be found under:

Computer Configuration, Administrative Templates, Windows Components, Internet Explorer, Pop-up allow list

Or

User Configuration, Administrative Templates, Windows Components, Internet Explorer, Pop-up allow list
