asp.net - SharePoint 2007 WebPart not accessible to any user unless a local user accesses it first -

We are experiencing a problem with a SharePoint WebPant that we have developed.
After every App Pull Process Recycle, the thw webpart is not accessible to any user unless a local user accesses the web page page first.
We recycle our application pool daily and unless a local user hits the webpage page, it is unavailable to all other users.

The error is: "Paaj was not found"
What could be the reason for this, it would be very useful.

Kind of

We had a similar problem on a recent project. Then the problem was that unknown users (guest users) did not have the right to load and compile the Web Part.

Our solution was to give the user that anonymous visitor requests were run as the right to read the folder where the web part files were stored.

So I suggest that you see the same things. Which user is impersonated when an anonymous user visits your page and the user has what rights. Most probably they do not have the necessary rights to compile or setup Web Part.
