If you choose not to purchase a signed certificate from a third-party CA, you may choose to install the self-signed certificate into the trusted certificate store on every client that uses Web-Portal. IE 7 must be run with administrative privileges to perform this change, and it must be performed on each client who will use Web-Portal.

Wildcard Certificates in Web portal not working with IE 7

Internet Explorer’s handling of wildcard certificates changes between IE 6 and IE 7, and for older versions of MSS, wildcard SSL certificates will not work in IE 7 with Web-Portal. A wildcard certificate is one that includes an asterisk as the hostname portion of the certificate’s common name. For example, a wildcard certificate for 3Com Corporation would have a common name of “*.3com.com”.

3Com recommends that you upgrade to MSS

5.0.11.4or later. The Web Portal feature now handles wildcard certificates in a manner that is compatible with both IE 6 and IE 7.

Windows Vista Driver interoperability issues

Windows Vista drivers are relatively new and have not yet reached the maturity level of Windows XP drivers.

3Com recommends that you use the most recent Vista drivers available from the manufacturer’s web- site. If that does not resolve the issue, you can try to run the Windows XP drivers for your wireless NIC; some of them may run under Vista and provide better results.

3WXM support in Windows Vista

3WXM does not officially support Windows Vista yet, so there may be some interoperability issues. Official support will be included in an upcoming release of 3WXM. Known issues include installer issues for the standalone client and the server, as well as intermittent failures to launch the Webstart Client.

3Com recommends that you do not run the 3WXM server on Windows Vista or Longhorn; use Windows Server 2003 instead. For clients accessing a 3WXM server who have no other choice of OS, run the Java Webstart client or use Microsoft’s “Remote Desktop” client to connect to a Windows XP computer and run the client from there.

Vista Client interoperability issues

Vista client PCs have an interoperability problem with a Windows 2003 certificate server. The Windows 2003 certificate server must be patched with some files from a Windows Longhorn server. This URL gives the details:
