When you add a filter, and tell it to save, you may get an error that it was unable to save to the xml document.
When you go back into the filters, it does not have the filter(s) you just added.
To fix this, you will need a copy of your filters from the last backup you have of them. This process is to be performed on one of your Central Computers that CGW was installed on.
1. Exit all consoles.
2. Open command prompt and change to the following directory: "C:\ProgramFiles\NetIQ\Change Guardian for Windows" (This may be on a different drive or path depending on OS version and options taken at installation time.)
3. On command prompt type: ConfigurationData.exe -w DefaultConfigurationdata.xml
4. Press Enter
5. Once this is done, reopen the Control Center Console and go through the Configuration Wizard to Change Guardian for Windows and import the filters again.
