Credentials deleted from Credential Manager

[dansmith65]

Under certain circumstances, all credentials disappear from Credential Manager after using this script. I have been unable to consistently reproduce this issue, but it did happen multiple times in various testing I did. If you enter your user/pass for fmsadmin at the "Confirming access to fmsadmin" section of the script, it's possible this will happen to you as well; so use this feature with caution!

It seems like this kind of thing can happen for various reasons, perhaps this helps explain the cause?

I find windows deletes the credentials if there are any issues with them. My thoughts are, this is to do with the security protection mechanism used to secure the credentials. We know the credentials are stored in a secure encrypted format. If windows is unable to decrypt the credentials it appears to delete them. This behaviour can be seen if you copy somebody else credential files and place them with your own.
