The specified ID file has been corrupted, or is not an ID file
What happened
You specified a User ID name in an User ID dialog box, but the User ID you specified is either corrupted or no longer a valid HCL Notes® User ID.
Note: Always
keep a backup of your User ID on a diskette, particularly after each time
you receive certificates allowing you access to additional Domino® servers.
What you can do
Use your operating system to replace the corrupted User ID with a copy of your backup User ID; or ask your Domino® administrator for a new User ID. If you must get a new ID, you'll need to get new certificates as well. If you had any encryption keys from other Notes® users and you still need them, ask those users to send them to you again.
