Dr. Watson

I am receiving a Dr. Watson error each morning when I boot up. It reads- An application error has occurred and an application error log is being generated. iexplore.exe
Exception:access violation (0x00000005)., Address:
0x01a8a078
We are running Win Nt 4.0
I have been getting this message for about 2 weeks and now when I open IE, it will open but crashes and I get that message again.
If anyone can offer some assistance, I will be grateful. Thanks for your help in advance.
