I would have to agree in part with Itzik.  However, if you use the
nslookup command, you will most likely find that your reverse DNS is
where the problem is.  You do not have to use local hosts files within
your NT network so long as all DNS settings are correct on the server.
The only time you should have to use local hosts is if perhaps you are
running two nics both on separate networks for load balancing.

We encountered a very similar issue and by investigating / correcting
the reverse lookup values, our issue was resolved.

Good luck,

Dan,
In this case I would believe Legato....
If you are using DNS, a bad primary server can cause a constant delay
for
every and each name resolution.
As you are on NT, I would suggest you add the server to the clients host
file
and the clients to the Networker server hosts file.
This way the name resolution for Networker purposes will always be done
locally.
More over, this could be a proof that Legato is right and your DNS setup
should be investigated or alternatively provide you with the definite
answer
to Legato's claim about name resolution.
HTH,
        Itzik

Subject: [Networker] Windows 2K Cluster backups extremely slow - 96 hrs
for
130GB


Sorry if you have seen this raised before.

I have a Windows NT backup server running 6.1.2 of Legato, backing up a
Windows 2000 cluster, containing three problematic drives.

Profiles 18GB 780000 files.  :- Causes high CPU util and never takes
over 48
hours to do 2.5gb.  We know the small files problem will cause some
overhead,
but this takes the p*$$.

User Data 130GB :- Backs up over 96 hours and will complete, again the
full
finishes just in time for another one.

Shared Data 130GB :- About 80 hours and will complete.

Note : All servers involved are at 100MB Full Duplex.

This has been reported to Legato who blame name resolution !!!! If name
resolution was the problem, we wouldn't get a backup at all.

Any ideas ?????

Regards,

Dan Francis
