Question : Is there anyway to reserve some resources in windows server so that RDC will still work in the event network/cpu is exhausted?

I currently run some very network intensive applications that have the potential to utilize quite a bit of CPU. Occasionally, the applications hit a funk and go haywire and lock up the machine to the point where I need a hard reboot to regain access to the machine via remote desktop.

Is there anyway to save maybe 10% of resources specifically so that I can get into the machine and stop the applications that are malfunctioning?

Right now all of the applications run as administrator, perhaps I need to change them to a different account and save the administrator account for these types of emergencies? I'm just not clear on whether or not doing that would actually preserve some of the resources so that I would be able to login as admin.

Any suggestions would be greatly appreciated

I use these utility functions :

Var MyVar:Variant;

begin
MyVar:=... // do some initialization

ShowMessageFmt( 'MyVar is of type %s and it's value is '#13#10'%s',
[VariantTypeName(MyVar),VariantAsString(MyVar)]);
end;
