Error 500 in weblogs for function AddComputerToGroup

Dec 7, 2016 at 5:45 PM
Hi

Have been using this webservice for a while now, works superb - great work
I have only been using the MoveComputerToOU before, no problems at all with
that function.
Now I have implemented the AddComputerToGroup function and it works perfect
if i deploy some machines, but I will run in an issue when I deploy some more
machines at nearly the same time :(
It seams like a problem with the application pool not being able to handle the
requests correct

This is the log from running 7 machines, 2 OK (200) and 5 Error (500)
