Subject: [ntdev] Re: Windows Error: “The Specified network name is no
longer available”.I checked it and your doubt is right. MTU is an issue in my case. I’m
appending a trailer of 5 bytes to the original packet. So when original
packet size becomes > 1495, miniport driver simply drops my new packet
which
now has size > 1500.
I thought of two solutions:
- Fragment the packet and send two instead of single packet. On the
receiving side, I don’t need to handle the fragmentation as it will be
handled by upper layer.- Set the MTU to 1495 instead of 1500.
The first option will take time to implement. Is there anyway of setting
the
MTU ?
Search list archives and docs for OID_GEN_MAXIMUM_FRAME_SIZE and think how
it could help you. Similar question was answered several days before.
If you have any problem with communication between two computers with your
IM driver modifying packets, Network Monitor is your friend. Actually, it is
essential tool.
