Windows Update checking/downloading new updates hangs Windows 2008 R2 Enterprise with TMG installed

Question

I'm fairly new to object-oriented program, so maybe this is a basic question, but I'd appreciate any help you can offer.

If I have a class B, which is derived from class A, is there some way for objects of class B to access class B's member functions from within member functions of class A? So in the example below I might have a call to function2 from within function1 if the object initially calling function1 is of type B. Is this possible, and if so, how do I accomplish it? Thanks!

   class A
    {
    public:
        int a;
        int b;
        A(){}
        A(int a, int b) { this->a = a; this->b = b; }
        int function1();// { call function2 if class B } 
    };
    class B : public A
    {
    public:
        int c;
        int d;
        B(){}
        B(int c, int d) { this->c = c; this->d = d; }
        int function2(); 
    }; 

Solution

It seems the problem is related to Time Difference between AD and TMG. Whenever the AD clock and TMG clock differs for 5 minutes (Kerberos setting can be changed to allow more time difference) it makes TMG unresponsive. Took us some time and "hangs" to figure it out!

Hope this helps someone else :-)

This isn't normal error in my case. I don't check for updates myself or anything. Automatic update checking hanged machine which had to be powered off for things to return back to normal.
