When mapping drives, intermittent 'The Specified Network Name is No Longer Available' messages displayed
Posted on 2006-10-24
I have several servers all set up with Cygwin scripts to mount a network-attached storage device and then run NTBackup. This works fine accross the board with a couple of exceptions. One server refuses to backup as it loses the mapped drive, presumably when I log off, but the script does not reconnect the drive. This procedure is in place and working for many other servers, including two on the same subnet as the faulting server, as the NAS is on a seperate backbone subnet.
This is driving me mad, I can find no explanation as to why this may happen. I have tried:
Checking FW logs for large volume of network traffic - not consistent with fault timing
Using command line to make mapped drive persistant - not helped
Deleted and reconnected mapped drive several times
I realise many people frown upon NTBackup, my thoughts are that it is good for what we require. It is the rest of the operating system that is messing things up!
What would be great is some sort of command line diagnostics relating to what network shares the machine has cached, if available?
Any suggestions are much appreciated, thanks for the help
