Hi,

I have a feeling someone may have hacked our server and might be abusing our bandwidth. Our Bandwidth usage has increased 10-20GB per month for the last 4-5 months. We are now apparently using 70GB more than we were apparently using in December ..... and it is still climbing at an alarming rate.

The trouble is, we have not put any new websites live that would generate anything close to this level of traffic - and even the december figure appears incredibly high. We have analysed the stats for our sites, and according to the logs, all our sites together are using under 5GB of traffic each month ..... but something is causing the overall reading of the server to be almost 100GB. So what could be causing the other 95GB of bandwidth usage?

Worse still, it is costing us several hundred pounds each month to cover the cost.

We are using a Windows Server. Does anyone have any ideas of what could be causing this, where I can find files on the server that might be causing this ..... or recommend any software (preferably free at first) that can scan / monitor total server bandwidth usage.

The guys who host our server are not very helpful. I think they are quite happy for this to continue - they are after all getting an extra few hundred £'s per month because of it. They seem to have no great motivation to help us.

Please please please help. All advice is more than welcome.

Appreciated.
Brian
