MS ISA 2006 Problem

[Liam_uk]

I am having a really strange issue with it in work, i've posted a question on Experts Exchange but i've not had any replies to point me in the right direction.

 

Basically whats happening is we have a group of users that use ISA 2006 to get internet access, they have a document management system that they need to upload to through a web interface, whenever they try to upload a file which is greater than 30mb it fails.

If i upload a file through Border Manager or any other internet connection it works fine.

I have tried lifting all restrictions on ISA for these users and still it fails. looked at all the config screens on ISA and nothing stands out.

 

any help much appreciated

Connection timeouts perhaps? Not being an ISA expert, I couldn't tell you where these hide unfortunately

One of the rules limiting uploads/download requests? we had that on 2004 and had to change the rule to 1GB!

Thanks for getting back to me, i had a look through the ISA config and can't see anything to limit upload or download file sizes. I've monitored the connection process and the only error i can see is this.
