Hi Folks. Sorry if this is a bit long Firstly ill introduce myself. My name is Barry and I have worked in IT for too long really but my Mac skills have gone awry over the last few years mainly due to lack of customers that were using them. I work with a design company in the UK. Some time ago we installed a Netgear Readynas 102 6TB file server. The PC's on the network access the Readynas really quickly. The two Macs however are really really slow, often taking up to 3 minutes just to open a folder on a share. Both Macs are running 10.11.3 El Capitan and are an iMac (24inch, early 2008). Other one is a iMac (retina 5k 27 inch late 2014). I have been trying at some length working with Netgear support to resolve this to no avail so far. We have even had a Netgear engineer remote into the Nas and make changes to the SMB settings and upgrade the firmware. Nothing makes any difference. Tried a new switch, swapped the port over to the one the PC is running on and just the same. I am out of ideas so I am hoping another Apple user may have had a similar problem as there must be a fair few using Readynas. The problem has been there for sometime but I gather it got worse with the latest OS upgrade. The only way I know to connect to other devices like the NAS is to use the GO menu in finder, put the IP address in using either smb for CIFS, afp, or nfs. Have tried them all. Same results. Is there another way of connecting or creating an alias? Another thing that sprung to mind last night when I had a light bulb moment is I remember a similar issue on a PC years ago where it was trying to resolve a connection to a local network server but was going off into the internet first to find it before eventually finding it locally. Could this be the issue here and how can I force it to search just locally if it is. I really hope someone can help as Ive been burning the midnight oil for days now trying to resolve this. Any help really appreciated.
