Important information for customers installing the update on computers not connected to the InternetWhen you install the update on a computer that is not connected to the Internet, you may experience long installation times together with a corresponding message that states, “Creating Native images for .Net assemblies."
This is caused by network requests to connect to “http://crl.microsoft.com/pki/crl/products/CodeSigPCA.crl ” Web site and look up the certificate revocation list for each assembly that Native image Generation(NGen) compiles to native code. Because the Exchange Server is not connected to the Internet, each request must wait to time-out before it moves on.
To resolve this problem, you must turn off “Check for publisher’s certificate revocation” on the server that is being upgraded. To do this, follow these steps:
- In Internet Explorer, select Tools, Internet Options, Advanced Tab.
- In the Security section, click to clear the Check for publisher's certificate revocation check box.
- Click OK to close the Internet Options dialog box.
We recommend that you clear this security option in Internet Explorer if the computer was in a tightly controlled environment.
When setup is complete, recheck the “Check for publisher’s certificate revocation” check box.
Important information for Outlook Web App users about Outlook Web App customizationWhen you apply an update rollup package, the update process overwrites the Microsoft Outlook Web App (OWA) files if it is necessary. If you have changed the Logon.aspx file or other OWA files, the customizations are overwritten to make sure that OWA is updated correctly. After you apply the update rollup package, you must re-create OWA customization in Logon.aspx.
We recommend that you always make a backup copy of any customized OWA files before you apply the update rollup. For more information about OWA customization, visit the following Microsoft Web site:
Note Make sure that you apply the update rollup to the internet-facing Client Access servers before you apply the update rollup to the non-Internet-facing Client Access servers.
For other Exchange Server 2010 configurations, the order in which you apply the update rollup to the servers is not important. For more information about CAS-CAS proxying, visit the following Microsoft Web site:
