Webpart troubles on the SBS2003 SharePoint "Companyweb" site

I am currently running SBS 2003 with ISA Server. One of the reasons I wanted to do this was that SBS by default comes with a Windows SharePoint Services site ("Companyweb") and I wanted to explore custom web part development.

Well.. I have not even gotten to that point yet. Playing around with third party web parts, I installed SmilingGoat's FeedReader web part to bring up some RSS feeds on my SharePoint site and I am consistently getting the following error message:

Searching for your RSS feed has timed out.
If you use a proxy server, please make sure the address and port are correct in the Web Part settings.
If you do not use a proxy server, please validate the RSS feed URL is correct.

I have configured the proxy name and the proxy port on the web part settings within the shared view of the web part AND this is a stable feed that I am going against (The KBAlertz SharePoint RSS feed) AND I have no issues accessing the Internet via the browser that is configured with the same proxy settings.

So I put that on hold for a bit and deployed the SmartPart 1.0.0.0 web part which enable you to host ASP.NET user controls within it. After installation of the SmartPart in the GAC via the install routine, I drop the SmartPart List onto the "Companyweb" page and choose the provided "Dropdown Navigation Sample" example. The site at that point dies with the following error:

The "UserControlWebpart" Web Part appears to be causing a problem.

I have to go and disable/delete the web part in order for the "Companyweb" SharePoint site to come up again.

I am wondering at this point if there is anything unique about the SharePoint installation on the SBS 2003 box or if anyone has encountered such an error before. Bit frustrating!

I would very much appreciate any pointers anyone can provide to troubleshooting this issue.

In the web.config, try to change the trust level from WSS_Minimal to WSS_Medium. The dropdown navigation uses the Object Model, so it requires Medium Trust. Contact me if you have any problems!

Thanks Jan. That worked! Is there any documentation out there that points to what the differences in the CAS permissions are between WSS_Minimal and WSS_Medium? Or do I have to work through the policy files?

<br>Hmmm.. Sounds like a good excuse to go read Maxim's stuff again :-)

Hi Anil &amp; Jon,
<br>
<br>I am experiencing a similiar problem. I am also trying to setup the SmartPart on SBS 2003. I am just not sure which web.config needs modifying as there are multiple copies on the server.
<br>
<br>Anil, if you would be able to clarify how you resolved this problem that would be appreciated.
<br>
<br>Regards,
