Important information for customers who install the update on computers that are not connected to the Internet
When you install this update rollup on a computer that is not connected to the Internet, you may experience long installation times. Additionally, you may receive the following message:
Creating Native images for .Net assemblies.
This behavior is caused by network requests to connect to the following website:
http://crl.microsoft.com/pki/crl/products/CodeSigPCA.crl
These network requests represent tries to access the certificate revocation list for each assembly that native image generation (NGen) compiles to native code. However, because the Exchange server is not connected to the Internet, each request must wait to time out before the process continues.
To resolve this issue, follow these steps:
- On the Tools menu in Windows Internet Explorer, click Internet Options, and then click the Advanced tab.
- In the Security section, click to clear the Check for publisher's certificate revocation check box, and then click OK.
Clear this security option in Internet Explorer only if the computer is in a tightly controlled environment. When the setup is complete, click to select the
Check for publisher’s certificate revocation check box again.
Update issue on computers that have customized Outlook Web App files
Important Before you apply the update rollup, make a backup copy of any customized Outlook Web App files. For more information about how to customize Outlook Web App, go to the following Microsoft website:
When you apply an update rollup package, the update process updates the Outlook Web App files if they are required. Therefore, any customizations to the Logon.aspx file or to other Outlook Web App files are overwritten, and you must re-create the Outlook Web App customizations in Logon.aspx.
