VNC over different subnet mask
Mon Jun 23 08:22:00 2003
Sorry, Fridays are a half day, so I didn't get any of the emails till this morning! I did manage to get VNC working after I changed the
subnet to 255.255.248.0, it just took a while to 'refresh'. I think my network card is having problems, it drops my network every now
and then, either need a new card or format and re-install windows.
I'm just reading through all the emails, learning a few things about TCP/IP that I didn't know before, especially with Corne's post,
thanks for taking the time to write such a detailed explanation.
Cheers for everyone's input

If the machines are on the same subnet the router is not involved. The
only way the MAC would be an issue is if the machine were talking to each
other before the move (which it seems they weren't). And the reboot to
change the subnet mask (assuming MS Windows) cleared out the local arp
cache anyway. We are all just pissing in the wind until Mr. Blackmore
comes back with more info.
