'Internet Explorer cannot display the webpage' issue

[quickeye2000]

Hi,

I'm having problem with the web interface. After a few minutes (sometimes seconds) I get 'page cannot be displayed' error. I usually have to wait some time before the logon screen shows again.

This happens at different times during the day. I have tried using IE 6 and 7 and Mozilla 3. Also tried from different computers.

MARS version 4.2.2

Thanks

Did you check your GUI logs for errors? And why are you running such an OLD version?

Thanks for your help. I'll check the logs for any possible cause.

The model is MARS 50. The data migration doc below says 50 cannot be upgraded to 5.3.x.

Can you tell me what is the latest release that can installed on a MARS 50.

Farrukh,

I found the answer at:

Thanks again

Yup thats spot on, for generation 1 appliances (Protego ones) 4.3.5 is the latest version. For gen-2 its 5.3.5 I think. Let me know how the GUI thing turns out.

Btw, if you have important data on your box you have to go through the upgrade process. You cannot directly install 4.3.5. You have to go through many updates in the middle to get this done. If the data/configs are not important and can easily be done again, you can just re-image your box from a boot-cd and that will take you directly to the latest version.
