Verisign Certificate Expiration
Netscape Communicator 4.05 or earlier include a root certificate set to expire on December 31, 1999. Users of these browsers will experience an additional dialog box when connecting to secure sites after January 1, 2000. This is a user interface issue; root CA certificate expiration does not affect SSL encryption. A user may safely click on continue and proceed with secure transactions. This is not a Y2K issue.
In order to eliminate this additional dialog box, the user must
upgrade their browser or delete and obtain a new root CA certificate.
This applies to Netscape Navigator 2.02 for OS/2 and to Netscape Communicator 4.04 for OS/2 Warp. Netscape Communicator 4.61 for OS/2 Warp has an updated root CA certificate and needs no action.
