How can you replace MSGINA.DLL?

[mtrax]

We have 2 WIN2K servers with SP3. One of these will not allow logging on, displaying a message along the lines of "MSGINA.DLL cannot be found or is corrupted please replace". The server can be accessed form the network.
I have restarted using a WIN2K CD and gone into recovery mode. Got to a command prompt and copied the file over. This has not worked.
I don't want to have replace the OS on a server which is part of the active directory. Is there any other way of doing this?
If we do have to put on a new OS does anyone have any helpful tips on potential problems of doing this.

You may need to repair the installation. Boot from the 2k Cd and hit R to repair.

Good luck.

(BTW, did this happen after installing PCAnywhere?)

Warning: Potential System Failure
Attempting to use a new GINA can cause a system to fail to boot correctly. If a new GINA is created, the registry is changed to use this new GINA, and attempts to restart the system are met with a Failed to Load xyz.dll error message.
Recovering from a GINA-related System Failure
Recovery is possible without reinstalling the system. This requires having a boot disk, or equivalent workaround, that will boot the system without using a normal hard disk boot.
To recover from this situation:
1. Boot the auxiliary system—potentially by using a boot disk.
2. Go to the System32 folder where the new, failed GINA DLL is located.
3. Move the failed GINA to a different folder.
4. Copy the original MSGINA DLL in the System32 folder and rename it with the name of the failed GINA.
5. Restart the computer and the original MSGINA DLL will load under the new name. At this point fixes can be made in the modified GINA
