I found that the VBS-plugins can modify that file and store their results there. But only when the field is not exists in the file.
I have admin field "fields_22". When it exists in admininfo.conf, script's results are ignored. It can to create correct XML like
<keyvalue>something I want to put there</keyvalue>
But these changes are ignored. Should I manually remove the lines regarding fields_22 from admininfo.conf. the changes will be applied. My 300+ PCs have wrongly filled admininfo.conf files. And I can't manually clean all of them. How to remove some records from these files to fill them with correct values from plugins?
