No, there is not a service that can be scheduled for reboot,You may be able to add a command line script,which I have no info how to.

There's a program called "Reboot IT" that costs $40. It will reboot your NT Server weekly. It operates as a service though.

You can download the shareware version at www.download.com

The NT4 Resource Kit contains Shutdown.exe, an application that will reboot your computer. You could get a copy of this exe, then script the shutdown.
I like to make BAT files and then schedule running them, instead of putting all of my commands inthe AT schedule line. So, I would do it like this:
1. Copy Shutdown.exe into the %windir%\system32 folder, so that way the default PATH statement will be able to run Shutdown.exe from any location. This will make the next step easier
2. Make a BAT file (call it shutdown.bat) and have it contain the line:
SHUTDOWN.EXE /R
3. Save the BAT.
4. Set up the schedule using the AT command to run the BAT file

That is it.
Hope this helps.

Use easy to use shutdown.exe from NT4 Resource Kit that can be downloaded freely on www.microsoft.com. After install the RK, run shutdown /? on command prompt to show available options that very simple. Then use "at" command to set the task. If at command confusing you, use the graphical at manager (winat.exe). Search it on www.microsoft.com/technet to get the download url.
