Microsoft Web Administration (MWA) may return an “Out of Memory” error when the MWA console is used to configure more than 1,000 users to a single Secure Sockets Layer (SSL) connection in Windows Vista. The error in MWA resembles the following:

System.OutOfMemoryException: Retrieving the COM class factory

You may also see the “Out of Memory” error in any application that is using DCOM. The error in a DCOM application resembles the following:

8007000e (ERROR_OUTOFMEMORY)

Note: This problem also occurs in Internet Information Services (IIS) 7.0.

Consider the following scenario.

• On a Web Distributed Authoring and Versioning (WebDAV) site, you set the Secure Sockets Layer (SSL) setting for client certificates to Accept.
• On a computer that is running Windows Vista or Windows Server 2008, a user adds this WebDAV site by running the Add Network Location Wizard or the Map Network Drive Wizard.
• After the user finishes running the wizard, the Select Certificate dialog box is displayed. In the Select Certificate dialog box, the user clicks Cancel.

In this scenario, you expect the user to obtain an instant connection to the WebDAV site or to receive a dialog box that requests the user’s credentials. Instead, the operation exits unexpectedly.

Notes

• When the SSL setting for client certificates is set to Accept, you expect the user to be able to provide a certificate or credentials to access the WebDAV site.
• This issue does not occur on a computer that is running Windows XP or Windows Server 2003.

Security Sockets Layer: Cryptographic protocols which provide secure communications on the Internet for such things as web browsing, e-mail, Internet faxing, instant messaging and other data transfers.

When a mail program tries to connect to a Microsoft Exchange Server 2007 server by using Secure Sockets Layer (SSL) over Simple Mail Transfer Protocol (SMTP) port 587, the connection cannot be completed.

This problem occurs if one of the following conditions is true:

• You are running Windows Mail on a computer that is running Windows Vista.
• You are running Outlook Express on a computer that is running Microsoft Windows XP with Service Pack 2.
• You are running Outlook Express on a computer that is running Microsoft Windows Server 2003 with Service Pack 1.

Note: By default, Exchange 2007 uses port 587 for SSL connections.

You use Internet Explorer 7 in Windows Vista to access a Web server that uses OpenSSL. Then, the server and the client negotiate to use the Diffie-Hellman cipher. However, the session is not established, and you receive the following error message:

Page cannot be displayed

When you open a Web page that uses Secure Sockets Layer (SSL) in Microsoft Internet Explorer 6, an access violation may occur. Additionally, you may receive the following error message:

Microsoft Internet Explorer has encountered a problem and needs to close. We are sorry for the inconvenience.

situation
SSL connections with Microsoft Internet Explorer 7 (IE7) on Microsoft Windows Vista RC2 will fail with:

• SSL enabled web services on Novell NetWare 6.5 and Novell NetWare 6.0
• Novell iChain 2.3 SSL enabled authentication pages and accelerator

SSL services on OES Linux (OpenSSL based) do not have this problem

Internet Explorer Version 7 on Windows XP does no have this problem as TLS 1.0 is not enabled as default security setting

Consider the following scenario. The network is running a Cisco PIX 515E firewall. A user tries to access a Web page in Windows Internet Explorer 7 by using Security Sockets Layer (SSL) from a computer that is running Windows Vista. However, the user receives the following error message:

Internet Explorer cannot display the webpage

This issue does not occur if the user tries to access the same Web page from a computer that is running Microsoft Windows XP Service Pack 2 (SP2).
