Workaround #1: Change the server configuration using the GUI as follows: Add the string 'administrator' (without the quotation marks) to the Deny login for users in User Restrictions. Create a subconfiguration entry in the Advanced screen by adding a UserSpecificConfig line to the end of the file, for example: "UserSpecificConfig New-Admin-Name admin.config" Click the Apply button to notify the running server of the changes. Create a file named admin.config in the folder where the server was installed (usually C:\Program Files\F-Secure\ssh server) that contains the following line: UserConfigDirectory "C:\\Documents and Settings\\administrator\\.ssh2" Note: The doubled \\ are required. Both the sshd2_config and admin.config files should have their file protections changed to permit only the Administrator group to access to these files. Workaround #2: Create a folder in the "Documents and Settings" folder with the renamed user name (such as, New-Admin-Name) and create a .ssh2 folder there (for example, C:\Documents and Settings\New-Admin-Name\.ssh2. Then move - do not copy - all public key files and the authorization file to this new folder. Remember to set the file protections on these folders to permit only the New-Admin-Name user access to these files.
