SYMPTOMS
The communication between two FDDI rings through an Ethernet segment may
fail when you use TCP/IP and any FDDI network interface card (NIC) in
Windows NT 3.5. For example:
CAUSEBecause both Windows NT 3.5 Server/Workstation are connected to the FDDI ring, the two hosts will negotiate to use the FDDI's MTU size. However once the communication between the two hosts begins the Ethernet segment will fail to forward packets more that 1500 bits. This situation may not occur if the bridges are replaced with routers, because router are capable of fragmenting packets (TCP/IP only). RESOLUTION
To correct this problem, modify the registry.
MORE INFORMATION
The MTU size specifies the maximum transmission unit size of an interface.
Each interface used by TCP/IP may have a different MTU value specified.
The MTU is usually determined through negotiation with the lower driver,
using that lower driver's value. However, that value may be overridden.
Ideally, the MTU should be large enough to hold any datagram in one frame.
The limiting factor is usually the technology making the transfer. Some
technologies limit the maximum size to as little as 128; Ethernet limits
transfers to 1500; and proNet-10 allows as many as 2044 octets per frame.
