| Description | Cannot register the URL prefix http://*:80/ for site 1. The site has been deactivated. The data field contains the error number. |
| Event Information | According to Microsoft: CAUSE: Typically, this issue occurs when one or more of the following conditions are true: 1. Another process is using port 80 or port 443 on the computer that is running IIS 6.0. By default, IIS 6.0 uses TCP port 80 as the default TCP port and port 443 for Secure Sockets Layer (SSL). 2. The ListenOnlyList registry subkey is not configured correctly on the computer that is running IIS 6.0. RESOLUTION: To resolve this issue, you must use the Netstat.exe utility on the command line to see if another process is using port 80 or port 443. If port 80 is not being used, you must then examine the ListenOnlyList registry subkey on the computer that is running IIS 6.0. To do this, follow these steps. |
