Something interesting i found while playing around with ISA 2004 (might even work with other versions too).

If you got a backup and forgotten the password, simple.

• Install ISA
• Create a backup of that server in a file and remember the password
• Open the backup file using notepad, copy out the MD5 hash
• Paste this hash inside the backup file which you’ve lost
• Import the backup with the password that you created earlier

OR, if you have at hand an MD5 hashing tool, just hash out the new password. Not sure if that would work tho…. (This is for the geeks who have hashing software in their mobile phones or favorite link in their browsers)There. Cool huh.
