SOAP and .asmx sites - 12.Dec.2006 9:42:22 AM

Hi all,

I have a problem and i think it's isa related.

At my company we have an internet application which adds some information about customers. I will log in at an .asmx site, all goes well. When i submit some info and try to update the fields (with a button on the site) the site will open a new browserscreen and i get the following error:

HTTP 500 - Internal server error
Internet Explorer

When i'm at home, there's no problem. But when i'm behind the ISA 2000 firewall this problem occurs.

The editors of the site tells me that there is a SOAP protocol who runs in the background. They also say that only port 80 is being used (i doubt that because i have no problem of surfing different kinds of websites).

Who can help me out? Are there any ports used by SOAP or asmx other than port 80? How can i fix this?

Thanks in advance.

Greetings,

Ramon
