9741.0. "network problems with LAT and updated V4.0B" by ALFAM7::STREPPEL () Wed May 07 1997 08:23

    For the first time in 2 years I did an update installation instead of a
    full one - with consequences. This was from 4.0A to 4.0B. We had
    terrible network problems - LAT failed, NFS timeouts, VMS cluster
    trouble - after the final reboot of the updated system
    and were looking into all sorts of possible causes for this trouble.
    
    We finally found out that it was my machine (a Flamingo) that caused
    the trouble. Disconnecting it from the net resolved the problem.
    Rebooting the old V4.0A kernel also solved the problem. Rebooting the
    new 4.0B kernel we found that the second when LAT was started network
    trouble began. On another node we got several LAT protocol errors.
    Stopping LAT solved the problem.
    
    Also building a new kernel by adding a couple of options that had got
    lost during the update - PACKETFILTER, CDFS, ... - and booting that
    kernel with LAT started solved the problem.
    
    Strange, isn't it?  It would be interesting if someone else has the
    same problem.
