There should have been a recovery key established when you encrypted the drive/partition. I would use that method as opposed to renaming files and deleting files. You may force your data into a "lock-down" state.

No key, no data.  I don't think you can do anything without the key.

Please be precise about the Bitlocker encryption. What protector did you use, TPM?
Long story short: yes, if the server still boots beyond Bitlocker authentication, then there are ways to reset all passwords. And yes, we may modify Bitlocker encrypted disks offline if we have the key.

Do: details please on the encryption:
TPM
TPM+PIN
Startup Key?

Ok, then we could solve it if you have administrative rights, but that's what you lack, that's why you try the offline modifications, right?

Since non-admins cannot reset BL protectors, we cannot circumvent BL. Thus, we cannot use any password offline resetters.
Your only bet is FireWire. If the machine has a FireWire port, you could use the FireWire hack. But FireWire on a server? Or is it desktop hardware?

That card would need to get auto-installed, so you would need to find one that works with Windows' built-in drivers. http://www.youtube.com/results?search_query=firewire+hack Shows the process.

If not possible, your last Resort is a cold-boot-attack: http://www.youtube.com/watch?v=JDaicPIgn9U

There are two videos at least...
The first link shows methods mostly based on the software Winlockpwn.
The softwares/devices used to read out the RAM in the second video: I don't know, but there will be instructions somewhere on the web if you google "cold boot attack".
