How to add a scheduled task that should run every x-minutes on Windows Server 2003 R2.
I have followed many suggestion from the web, but I always end up with some interruption after 1 or 2 runs.
Here is what I did:
New Scheduled Task
Schedule > Daily Task 08:00 AM, every 1 day
Schedule > Advanced > Repeat task every 30 minutes, duration 31 minutes (why???)
Enabled it
Not working after 1 run and the next run time is +1 day at 08:00 AM
How to fix this problem?
Your configuration steps are correct... what is in the log? C:\Windows\Schedlgu.txt

I think you're technically right in thinking that you can't set it to run every 15 minutes after a boot, but why does it matter so much? E.g 
Will run the task every 15 minutes of every day. You can add in a new schedule alongside it to run on startup aswell. Worst case scenario there being that the task may run twice in less than 15 minutes for the first time after boot.
If that really is an issue, then the only alternative way I can think of is to come up with a script which runs at startup which creates the new scheduled tasks. You may be able to use this page as a starting point:

So, to clarify:
1) Server boots
2) Scheduled tasks runs batch file
3) Batch file deletes the previous boots scheduled tasks (You can use an ID number to differentiate)
4) Batch file creates a new task to run at 15 minute intervals today
5) Batch file runs the task
You may be able to skip some of that by just having the bootup scheduled task run the 'real' task for the first time. It will then run every 15 minutes from that point. However, it still doesn't preclude the possibility of running it more than once in 15 minutes.

It sounds like the task might not be completing successfully, and multiple instances of the task might be trying to run at the same time.
Open up Scheduled Tasks from the Control Panel.
Right click on the task you've created and click "Properties."
Navigate to the "Schedule" tab.
Choose the start time (00:10 AM)
Make sure that Schedule Task Daily is set to Every 1 day(s).
Click Advanced.
Check the "Repeat Task" checkbox.
Until: (select bullet) Time: (enter 11:59 PM) and click "OK"
Open the "Settings" tab now.
[Check] Stop the task if it runs for: [0] hour(s) and [9] minute(s). Click "OK" This will prevent multiple instances of the scheduled task from running at the same time, possibly causing the conflicts you've described.
If the scheduled task is set to run every 30 minutes, set it to stop the task after 29 minutes (in case it hangs for some reason).
If this is the problem you'll want to look at what your task is doing, and see what might be causing it to hang. A successfully executed task will exit with Last Result = 0x0.
