Cant access NAS please help

[p.l]

Hi Guys.

So we updated to El Cap and it somehow blocked our NAS access
So i went back to Yosemite and I'm getting the same error?

Can someone help???
Not sure what to do, Currently 3 windows and a Late '12 iMac on Mavericks can access the NAS but not me.

Im on a late '13 iMac at the office.

Thanks

Are you accessing using a name or an IP address?

Username, We have changed it a couple of times to try get in with different accounts

I'd be surprised if you haven't tried this, but I suggest determining the NAS's IP address and then telling Finder to connect to that address.

Yeah, a friend had the same issue. Select Connect to server from the Finder's Go menu, then use the format:
smb://username@IPaddress/sharename
