When you type a fully qualifed domain name (FQDN) in the Printer Name or IP Address box in the Add Standard TCP/IP Printer Port Wizard, you may receive the following error message:
This error message occurs if the host name or any of the domain names in the FQDN is longer than 16 characters.
The address is not valid. Please enter a valid address and try again.
In addition, the Standard TCP/IP Port name should not exceed 48 characters or use extended characters such as "/". If it does, this may generate an error message when you attempt to delete the SPM port and the port may not delete. The only way to delete these port entries is via the registry under:
HKLM\System\CurrentControlSet\Control\Print\Monitors\Standard TCP/IP Port\Ports\[problem port name].
The Add Printer Wizard does not accept an FQDN that contain entries that are longer than 16 characters.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
