Desktop does not appear

I am using windows 2003 server. My problem is Desktop doesnot appear after login. How to fix it.

Open the run box. If you can't get to it by using the windows key or alt S, then hit ctrl alt del and open the task manager, file, new task.

Type explorer and press enter. The desktop should appear.

Is it happening on the administrator account only?

I tried to your idea. But the desktop is not appear.

Please reply any idea.

system restore?

Before you try a system restore, see if there are any conflicts, hardware and software. Look at the device manager for hardware conflicts and disable everything under the startup tab in msconfig to test for software conflicts.
If that doesn't work, backup all data and try the system restore.

A.Kannan, I honestly have to ask why you are still attempting to manage Windows servers.

First of all be specific in your post. The "desktop does not display" is not sufficient information to solve your problem. After more than two years of asking questions by now you should know that.

Is it that your desktop icons are not displaying, or is your Explorer Shell not loading? In other words, can you see your task bar, start button, systray? or is nothing loading period?

What specifically were you doing immediately prior to this problem?
What event occurred? A reboot after install? Power Failure?

Apparently at this point you haven't even tried booting to safe mode to check your event logs? You have a very good chance that your event logs will tell you exactly what the error is and provide clues to how to resolve it.

I have no idea why I'm telling you all this. These are things you should know by now and be doing on your own. I'm not trying to sound mean, but really, what are you doing in this industry if you can't solve some of these simple problems on your own?

Check the mfg's site of your computer, they may have updated drivers and software patches that will solve most of the problems the MS updates are causing.
