Old Cisco ACS 4.2 on Windows lock notice help!

[Belisarius]

• Like the title says, I've been handed a system that I'll need to upgrade but I cannot for the life of me get into the Windows OS where ACS is installed and haven't a clue how to get around it. 

I have intermittent Web browser access. I can get to the admin web portal where do I disable this thing so I can get in and fix and upgrade this thing.

I need in. Safe mode doesn't work either. The lock screen reads: "Application functioning normally. Please use the browser to access"

This is a virtual machine. Access goes down I have to connect it to a workstation with a virtual serial cable that sometimes works.

Please help! How do I disable the lock notice and get into the OS.

Ok all, so I am just a lowly engineer and yes the stakeholders are still dragging their feet regarding "upgrading" to ISE. No matter what I tell them, i just get the "curriculum is not approved for ise" thus THOU MUST use Cisco ACS 4.2 on Windows 2003 Server.

I mean how much value does the class provide to the student if it’s using such ancient software right?

THATS WHAT IM SAYING XD. I'm dealing with non-IT people that just do not get it. I mean its best use case is to be a museum piece. Alas I'm required to keep it alive.
