Dave...my luck ran out this last night.  A log backup hung up on one of my 2 
clients that has been giving me trouble.  Back to the drawing board for me.  A 
whole 48 hours of backup bliss......

I found something on my search for answers related to nsrauth methods.  I know 
that in the beginning of this hangup and i/o 995 errors, we tried setting the 
Networker server to use just "0.0.0.0/0,oldauth", BUT, I don't remember if we 
set the clients to the same settings. I have been testing setting the nrsauth 
to "0.0.0.0/0,oldauth" on both the server and 2 clients in question over the 
last 2 days and so far, I have not seen the 2 clients in question hang up or 
fail. Still too early to tell, but so far so good.

Dave, are you using these settings or do you have "0.0.0.0/0,nsrauth/oldauth"?  
Just curious if you don't and if you would see any improvement using just 
oldauth.

What the NSR_KEEPALIVE_WAIT environment variable does is essentially ping
the NetWorker server from the client. That 3500 setting might too high
though. The idea is that it keeps network ports from being prematurely
closed by a firewall, so the proper setting depends on how the firewall
involved is configured. As such, this environment variable is only
relevant in situations where the NetWorker server and the client in
question sit on opposite sides of a firewall. If the client and server are
on the same side of a firewall, you are barking up the wrong tree by
activating that variable.

You might also look into doing some tuning of the client's TCP/IP
variables. I am not a Windows expert, but as I recall, those parameters
are changed via registry settings. If setting the NSR_KEEPALIVE_WAIT
variable to a value that your network administrator recommends still
doesn't help, then ask EMC or check on PowerLink to see if there are any
recommended TCP/IP parameters for Windows 2008 that might be worth
changing on the client. If this issue happens with many clients, fine
tuning the TCP/IP parameters on your NetWorker server might also be
necessary.
