First you'll have to find out which web part it is.  Obviously its going to be a web part that is non-standard.  When you find it, you need to make sure that the web part dll is registered in the GAC on all of your web servers and then in your web.config file that is found in your virtual server root (C:\inetpub\wwwroot if SharePoint is your default web app) and make sure your web part is registered as a safe control.


Here are a couple of entries from my web.config file:


    <SafeControls>
      <SafeControl Assembly="System.Web, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="System.Web.UI.WebControls" TypeName="*" Safe="True" />
      <SafeControl Assembly="System.Web, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="System.Web.UI.HtmlControls" TypeName="*" Safe="True" />

When deploying webparts to another server  you get this error("A web part or web Form Control on this Page cannot be displayed or imported. The type is not registered as safe") even if you have your webpart registered as safe in the web.config, don't stress its the namespace, your namespace doesn't have to contain spaces rather use dots or _ for spaces of the webpart name , especially if you are going to deploy the webpart to another server.

Hi Sweety,
                       How are you!

                      Its very simple, go to central administration --> Solution Management ---> select your webpart solution and click on the webpart solution then select the web application as you want then deploy it.

                     Next step is go to site actions --> site settings--> webpart --> and new webpart add the solution webpart as you deploy in central admin tool.  Then go to home page refresh the page, edit page, then add the webpart.

Regards,
Venkatesh

If you are deploying a web part through a wsp file, make sure you not only deployed the solution to the web application you first did the stsadm command on, but on any other web application that you would like to activate the web part feature on.

stsadm -o deploysolution -name "name of the wsp.wsp" -immediate -allowgacdeployment -force -url "http://myurlhere:81"

stsadm -o execadmsvcjobs

repeat this for each web app (aka port) you want to activate your web part feature on. eg:

stsadm -o deploysolution -name "name of the wsp.wsp" -immediate -allowgacdeployment -force -url "http://myurlhere:82"

stsadm -o deploysolution -name "name of the wsp.wsp" -immediate -allowgacdeployment -force -url "http://myurlhere:83"

stsadm -o execadmsvcjobs

etc

This command registers your web part as safe at the web application level, even though your web part feature is scopped to the site collection level. So you may need to activate your site collection feature to deploy the web part on each site collection. But you only need to run the stsadm commands above on each web application you want to run the web part on.
