You only have 2 possibilities:
1) If available, you may be able to modify the registry from another system on the network. You will need to know the Network name of the system. Run REGEDT32 from the server (or another workstation), and see if you can access the registry of the problem system. The key is HKEY_LOCAL_MACHINE / Software / Microsoft / Windows NT / CurrentVersion / WinLogon and the entry is GinaDLL. If you can delete the GinaDLL entry (which will have a path and IMGLOGON.DLL, e.g. \WINNT\MYTPEN\IMGLOGON.DLL), then restart the system. This will revert back to the default Microsoft logon 2) Use the emergency repair disk and run a repair on the system - if you have the appropriate Resource Kit & utilities, there may be some other options to work with the registry.
As a quick overview your options are to get the file back in place somehow (which will require some sort of utility), delete the registry entry as above (which may require some other utility), or use the repair (or re-install option) to put things back to default.
The safest approach would be to get at the registry & simply remove the GINADLL entry.
