i used the following command and it worked great... not sure if it cleaned up the other tables.
sqlcmd -U username -P password -d lansweeperdb -Q "delete from tblcomputers where computer = 'computername'"
lansweeper is on our sql database server. if it cleans up the database that will be great, we plan on putting this in our custom actions and using it two ways... one as a straight delete this computer from lansweeper, and to delete the machine before we change the computer name.
Please let me know if there are any other tables that need to have the info deleted.
Thanks
Brian
