Hi -
You are getting a STOP error in Windows. You didn't mention what OS you are running. Were there any installs or driver updates applied to this server that could cause the error to occur? Here are some steps to take, but you may want to confer with your Microsoft support before moving forward. Your Unity application will NOT be harmed by attempting to boot using Last Known Good Configuration, especially since you cannot get the server operational.
To troubleshoot STOP message 0x0000001E
1.Check that you have adequate disk space, especially for new installations.
2.Disable the driver identified in the STOP message or any newly installed drivers.
If you can't start your computer, try starting it in the Last Known Good Configuration or safe mode, and then remove or disable newly added programs or drivers.
For more information, see "Safe Mode, Last Known Good Configuration, and Other Startup Options" earlier in this appendix. If you cannot start in safe mode, see "Options to Use When a System Will Not Start" earlier in this appendix.
Important When you use Last Known Good Configuration, system setting changes made after the last successful startup are lost.
3.If you have a non-Microsoft-supplied video driver, try switching to the standard VGA driver or to a suitable driver supplied with Windows 2000.
4.Ensure that you have the latest system BIOS. Contact your hardware manufacturer if you need assistance in performing this step.
5.Restart your computer. At the startup screen, press F8 for Advanced Startup options, and then select Last Known Good Configuration.
