The Desktop icons cannot display after booting.

I'm using Shiron SR256L equipment,
Equipment: RG384B Intersky Remote Gateway,
Operating System: Windows NT
Software installed: Symatec, Mavis, Common files, Ati multimedia.
Error message: Eventlog file is full

Attempted solution: I only manage to navigate through Ctrl_alt+del to lunch the necessary programs i needed for my internet connectivity, which is not accessible to other assistant person on my network.

What can i do to solve the problem. "Desktop icons fails to come up after window finish its booting"
