I'm trying to figure out how to query for the MaxMTU in the Registry under HKEY_LOCAL_MACHINE System\CurrentControlSet\Services\Class\NetTrans\
Now the problem is when you install another network driver other then TCP/IP like IPX/SPX it adds more subkeys like \0002 \0003 One of those subkeys contains 0.0.0.0 for the DUN IP address and the MaxMTU is in that same subkey area, how do i query the MaxMTU value in that same area?? Each computer seems to have the MaxMTU located in a seperate Subkey under NetTrans\, sometimes its in NetTrans\0000 and sometimes its in NetTrans\0002 depending on how many network drivers they have loaded. One of my systems has clear up to \0008 and the MaxMTU is located in like \0005.
I will add more points for a thorough answer! Thanks in advance!
