关于updcrl.exe和verisignpub1.crl
The “verisignpub1.crl” is the file contains the list of the sites that have security certificates distributed by Verisign. This file is used by Internet Explorer and Outlook to provide access to these sites.
The “updcrl.exe” is used for updating.
This is not required operation. If you do have problems you may skip this command.

我来尝试,能否评论?@@
