Network name no longer available?!
Very odd problem this morning!
Came in to find some machines that were working fine just dropped their connection to either Exchange, file server or database server and throwing up "network name no longer available" errors :confused:
Some are fine, others then come back up... all on different switches, no errors in DNS or AD. Internet still works, ping still works and it's not every PC!
Just had one say "attempted operation on a non existent network connection" even though the connection is still live with an IP!
I'm wondering if the core switch has thrown a wobbly (5308xl) as it hasn't had a power cycle in about 2 years, any other quick suggestions?
