You might receive the following error while updating Microsoft Exchange Server version 4.0: When upgrading to Microsoft Exchange Server version 5.0, you might receive the following error:

The following two files in the <WINNT>\SYSTEM32 directory are either missing, corrupt or you do not have permission to access them:

If the files are there, check to make sure that you have the correct permissions to access and write to those files. If you have the correct permissions, then you may need to rename the files and expand them from the Windows NT Server compact disk.

These errors can also be cause by a corruption in the performance counter descriptions in the registry. For more information, please see the following article in the Microsoft Knowledge Base:
