network path not found iis server

We just cloned our iis server to a different host and cluster so that we can update the vmhost that it was on.  we also extended drive c:  on the vm cause it was running out of space.  When our users connect and run a batch from the web application (which connects to a database) they are getting the following " network path not found".  We can ping server by name and ip so we know thats not an issue and we can get to the folder / path that its saying  it cannot find.  We checked logs and are getting the following on the web server:

Issue didnt have anything to do with sql it had to do with bcp call that was being made to sql.  We opened a ticket with the software vendor
Check on the new server if you have any "ghost" network card due to cloning the server.

On the server, open a cmd window (with Administrative priviledges in case of W2008 server) and type

set devmgr_show_nonpresent_devices=1
start devmgmt.msc

This will open the devices console. On this console, go to View->Show hidden (or non present) devices (sorry for the translation).

Check on network cards and see if you have several "ghost" or nonpresent network cards. Delete them, and reboot.

Did you clone or migrate the server? If you cloned it & didn't sysprep the server, having 2 of the same server on the network will be a big problem.

we tried that but no joy...


Server was cloned.

we downed the first server before bringing the new one online, and made sure that it was on the domain.
See if the firewall on the server is blocking Netbios (meaning "file and print sharing").

If not, you may have to go to the PDCe and flush the netbios cache, or ARP cache that point the IP address to the wrong MAC address. That's the problem with cloning or VM ware. When networking the IP may stay the same, BUT the MAC address will always be different.

Still investigating tables within SQL to see if that could be the cause of the error.
