Failed backups

I have a problem with the full backup for 1 database on each of 2 different servers failing. The only thing I can figure is that it is the largest database on these two servers. It appears to write the file to the primary location (despite the error message) but does not write the file to my copyto location. Any help is appreciated.

Error message:

    Hi Heather,

    The most common things to look into are DNS and network latency issues. You can use the NSLOOKUP utility to make sure that's working, although there is no guarantee that there still isn't some DNS problem during transfer. So checking the application and system event logs for DNS failure may help.

    You may also try setting the NETBIOS protocol timeout to a higher number if the network is slow. To do this, set the registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters\SessTimeout=00000384

    Thanks for the reply. I will attempt to change the registry setting. I have several other databases on these 2 servers and they all have no problem backing up. I will let you know what happens once the registry setting is changed and I have ran a backup.

    We changed the setting on one of the servers and I ran it during the day and it worked. We are going to let it run this weekend as scheduled to verify that it is truly fixed before changing the registry on our Cluster.
