I have a couple of doubts about the Windows Sharepoint Services.

I wrote an application using Windows SharePoint Services, Office
InfoPath and Webparts done in c#.

This application is working fine, but when I try to access it from
a workstation (WinXP, same domain as Windows Server 2003) doesn't work
anymore and I just don't have a clue why's that... Does it could be an
authentication/permission problem?



The second doubt is about the deployment of this application.

I create a site template based in my webpage and that's fine, but
how I can deploy the webparts in my costumers in an easy way? I mean, is
there an easy way to deploy the webparts or do I have to follow all of
that steps (like put the assembly in GAC, generate the strong name...)
to deploy the WPs?
