Alright here's one that has me stumped.

prior to upgrading the client to v 4.5 the NT 4.0 machine running SP6a had the 
NBU 3.4.1 client installed on it and was able to perform both file system 
backup as well as SQL SRVR backups without issue.

Now that my customer has installed the 4.5 client (MP2), the file system 
backups fail with a status 41, but the SQL server backups run like a dream.

We've done the normal TS work, by increasing client connect and client read 
timeouts...

I know there is an issue with NT 4.0, SP6a and Exchange Server when the NBU 
client installer loads a newer version of mscvrt.dll...but I don't think this 
is related.  

We connect to bpcd, which spawns bpbkar, from the admin console it shows that 
we have connected to the client....but then it eventually times out.


Any ideas?
