We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
After you create a new Web site in Internet Information Server (IIS) and you attempt to start the new site, the following error message may occur:

Winsock Error: Can't assign requested address



CAUSE
This error can occur because the IP address that was specified for the IP address of the new Web site is not bound to the Network Card on the server.



RESOLUTION
To resolve this issue, add the new IP address to the IP Protocol tab by performing the following steps:
 * 1) In Control Panel, open Network Properties and choose Protocols.
 * 2) Select TCP/IP Protocol and choose Properties.
 * 3) Click Advanced.
 * 4) Add the IP Address and the Subnet Mask.
 * 5) Click OK until you return to the desktop.
 * 6) Restart the Web server.



MORE INFORMATION
If you have added all the IP addresses that you can through the interface, see the following article to add the additional IP addresses to the registry:
