This is an oldie but a goodie that I thought was worth a mention here. We originally published this last year but if you haven't seen or heard about it then it's worth a quick look.
Microsoft's own Steve Rachui recently posted a great article on his blog about a tool he wrote that will verify that your provisioning and AMT client certificates in System Center Configuration Manager 2007 are properly installed and configured. Configuring certificates can be tricky so this should be a great tool to use if you’re troubleshooting an issue you suspect is cert related or if you’re simply setting it up for the first time. To learn more and to download the tool visit:
