DOCUMENT:Q185496 01-MAY-1999 [iis] TITLE :Changing IP/Port on SSL Web May Require Key Manager Change PRODUCT :Internet Information Server PROD/VER:WINNT:4.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Internet Information Server 4.0 ------------------------------------------------------------------------------- SUMMARY ======= When a server certificate is applied to an Internet Information Server version 4.0 (IIS) Web server, the server certificate must be bound to the IP address and port number. If there are multiple certificates loaded but not bound, the server may not use the certificate correctly. MORE INFORMATION ================ Secure Socket Layer (SSL) connections may fail if the settings in Key Manager are incorrect. By default, Key Manager sets up IIS to use the certificate on all unassigned IP addresses and all unassigned ports. Unassigned means IP addresses or Port combinations are not currently bound to a certificate. If you bind a certificate to a specific IP address or Port and then change the IP or Port combination of the Web server, you must also change the setting in Key Manager. Example: If you have a Web server, www.myserver.com, on IP address 10.56.65.200 and port 443 (for SSL traffic), the server certificate must also be bound to 10.56.65.200:443. However, if you change the server address to 10.56.65.201:443, you must also change the setting to 10.56.65.201:443 in Key Manager. If you do not, IIS does not service requests for the new IP address and Port because it is still bound to 10.56.65.200:443. ====================================================================== Keywords : Technology : kbiisSearch kbiis400 Version : WINNT:4.0 Issue type : kbhowto ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
