SUMMARY
The Windows NT 3.5 Resource Kit documentation was not updated properly from version 3.1, and lists a number of invalid TCP/IP registry parameters. The parameters listed in this article should be used in their place. The Windows NT 3.5 TCP/IP stack was changed significantly from version 3.1, so many of the old parameters are no longer valid. The Windows NT 3.51 Resource Kit should include the necessary corrections.
MORE INFORMATION
Page 586 of Appendix B in "Optimizing Windows NT" from the Windows NT Resource Kit version 3.5 describes the RouterMTU registry parameter. RouterMTU functionality was replaced in Windows NT 3.5 by PMTU Discovery, as defined in RFC 1191.
For additional information on the usage of the RouterMTU parameter in Windows NT 3.1, see the following article in the Microsoft Knowledge Base:
