Hi,
I'm having a strange issue.
We have a 2012 file server (clustered), now when a user emails a UNC link to a file (excel)on this file server, everyone in the company (250-300 users) seems to open this at around the same time and then all resources on the server then seem to be denied.
Not just to this file. No failover, just unable to access anything else on this server.
Here's what nagios tells me, No memory issues, A cpu spike to 20%around the time.
Nothing in the cluster log, nothing in application,system event logs.
The network card is 4*1gb/s teamed (nagios/whatsup gold say this isnt being hammered)
Any ideas on how I can troubleshoot further?
Phil
