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:
This behavior is caused by network requests to connect to the http://crl.microsoft.com/pki/crl/products/CodeSigPCA.crl
Creating Native images for .Net assemblies.
(http://crl.microsoft.com/pki/crl/products/CodeSigPCA.crl)website. These network requests represent attempts 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 moves on.
To resolve this issue, follow these steps:
We recommend that you clear this security option in Internet Explorer only if the computer is in a tightly controlled environment. When setup is complete, click to select the Check for publisher’s certificate revocation check box again.
