SYMPTOMS
When you edit the Tcp1323Opts registry value for the TCP/IP protocol in your Windows 98/95-based computer, it does not enable RFC 1323 options as documented in the following article in the Microsoft Knowledge Base:

Also, changing the Tcp1323Opts registry value has no effect on the behavior of the TCP/IP protocol on Windows 95 and Windows 98.
CAUSE
There is a problem in the TCP protocol driver (Vtcp.386) when reading and implementing this registry value.
