Health_Chk retrieves FRS-related state information from the specified domain controller or server and stores this information in text files. These text files provide administrators with in-depth data that can be used to monitor or troubleshoot an FRS system.
Health_Chk can take quite a while to run. The script may collect huge amounts of data. This is especially true if you encounter problems with full staging areas, though staging area problems are not common on computers running Windows 2000 SP3 and later.
The text files are written to a specified directory using the name of the target machine.
Note
