Computers with Wonderware ActiveFactory 9.x clients installed, and which do NOT have access to the Internet can exhibit extremely slow start up behaviors. This is caused by the fact that the Windows operating system attempts to:
- Verify the product certificate.
- Check whether the certificate used to sign application libraries is on a Revoked list provided by the certification authority.
In other words, Wonderware ActiveFactory is a set of Microsoft .NET libraries. These libraries are digitally signed by Wonderware using a certificate issued by a root certificate authority. Examples of root certificate authorities are Verisign, Thawte, GoDaddy and others.
Note: Root certificate authorities maintain lists of revoked certificates. Certificates may be revoked if they are used by software identified as malicious. The Windows operating system checks at application startup to see if the certificate used to sign the application being started is on the list of revoked certificates.
Procedure
1. Open Microsoft Internet Explorer.
2. From the main menu select Tools > Internet Options.
3. Click the Advanced tab and scroll down to the Security section.
4. Uncheck the Check for publisher’s certificate revocation option and click OK.
5. Repeat these steps on each machine that lacks access to the Internet.
