On our network, we have a buffalo link station NAS device, I used to be able to access from any computer on the network. However now, I can access the NAS from any client machine on the network, except the one server that i need it to be able to connect to, that is our mainserver that has an LTO4 tape drive for backup. Whenever i try to map the network drive, i get the error "The specified network name is no longer available". However it is still pingable from the mainserver, and i can still access the web management page from the browser on the mainserver.

After alot of research, i kept running into articles that stated that the problem's cause is most probably the symantec endpoint protection 11.x that i had installed and then removed right after I started getting the "The specified network name is no longer available", i tried upgrading the symantec endpoint protection management console to version 12.x, however the error is still there.

If i don't manage to map the network drive to the mainserver, i won't be able to include it in the backup tapes unless i do a workaround.

I'd appreciate any pointer on how to continue the troubleshooting, thanks.

Mainserver: Windows server 2003 R2
