Could not load file or assembly and Failed to grant minimum permission

[Zac5]

Hi,

I have the same asp.net web application installed on three seperate windows 2003 servers. In one instance the application works perfectly however on the other 2 instances the application works intermittently, but when it fails I need to restart IIS for it to work again. There doesn't seem to be anything specific that causes it to fail, you simple cannot access it once it has gone down, it seems to just drop. I am using .NET Framework 2.0. I have tried the following so far:
1. Changed securty policy to full trust
2. added this line in web.config within <system.web>: <trust level="Full" originUrl="" />
still no luck.

The following error can be seen when you try to access the application:

.Interop error '80131417'

Could not load file or assembly 'xx.Utilities, Version=x, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Failed to grant minimum permission requests. (Exception from HRESULT: 0x80131417)

Any ideas anyone please?

have you tried restarting the application pool at regular intervals?

Thanks for you reply engjohn however...

this is not an option as the application is dropping upto several times every hour so restarting the pools at that frequency is not an option as this would take down ALL the pools and restart them. I think there is a conflict between some server setting and the application, as the same application is working fine on another server.
