IE 6 crash when entering some sites on W2K

[eroka]

Hi,
I have W2K 5.00.2195 with SP3, and I run IE 6.0.2600.000 (128-bit). I have Sun'S Java 2 also installed on the system.
When I enter certain sites the IE windows just disappears and obviously I cannot access the page. This is not followed by a total crash of all the rest of the IE windows opened on other sites, not does it cause any generation of an error message.
The Event Viewer does not state any problem that the system encountered.
An example of a page that I cannot access:

http://www.rest.co.il

But it happened on other pages as well, without any clear indication why that happenes.

Thanks for helping!
E.
