'An error occurred constructing the tree from the XML provided by the server: An error occurred retrieving the tree XML from the server. Undefined.'
Here are some suggestions for getting this issue resolved:
1. Locate the following files ('C:\Windows\Downloaded Program Files' or from IE Browser window 'Tools > Internet Options > General tab > Temporary Internet files section > Settings button > View Objects'), make a copy and place them in a different location as backup, and then delete them from the referenced location:
Altiris Clipboard Helper
ComponentOne FlexGrid 8.0 (UNICODE Light)
Note! The deleted files will be re-created when you enter the NS Console.
2. If this does not work, run a repair of the NS Server, All solutions, and any installed hotfixes from Add or Remove Programs. Please avoid terminal services or using the /Console switch for the repairs.
Note! Make a backup of your Altiris database first as a precaution.
