Slow accessing shared folders off SBS2011

Hi,
  I have a HyperV / Windows 2012 that has three VMs - (1) SBS2011/DC  (2) Windows 2008 R2 Terminal Server (3) Windows 2008 R2 App Server running Quickbooks database.

  The problem is when users log on to TS using Remote Desktop from their computers and click on mapped drives to Shared folders off SBS2011/DC, there is a long delay.
  I removed Symantec End Point Protection, but it is still hesitates. I checked the Intel RAID management and all is "optimal".
  Can you provide some suggestions where I begin?
  I saw an error in Event Viewer about Exchange Event ID 218 that suggests that I run Best Practice Analyzer for Exchange server. But I can't find Best Practice Analyzer for Exchange either on the SBS2011.

Thanks.

BPA for Exchange is in the toolbox within Exchange Management Console.
However I doubt if that is going to tell you anything.

There is an SBS BPA, which you will find the links to here: http://sbsbpa.com/ 

My instinct though is that the network isn't setup correctly and the delay is a time out. Could be your DNS isn't configured correctly, using external or a router for the DNS server, rather than the SBS Server itself. Was the server configured with the wizards?

SBS2011 TCPIP Settings@Simon
Sorry for not getting back to you. I have been tied up.
"Could be your DNS isn't configured correctly" --->
No one is having a problem accessing Internet or mapped drives. It is just intermittent delay/hang. Yesterday I removed "Network Protection" in Symantec EndPoint Protection from workstation computers. Let's see if that helps.
Also I am working on a number of errors in the Event Viewer of SBS2011. There are exchange database errors and other errors that might be causing this problem.

All workstations receive IP info from SBS2011 DHCP server.
Address Pool: 192.168.100-254
Scope options:
003 Router: 192.168.1.1  
006 DNS Servers: 192.168.1.5
015 DNS Domain Name: DomainName.local

Did you run the SBS BPA?

Simon,
 
 Sorry for a long delay. I have been busy ... but I am going to try to run BPA in the next day or so and will keep you posted.

 As to the delay accessing Shared Folders on SBS2011, the problem seemed to have been resolved now. Below is what I had to do:

 (1) There was an exchange database performance error in the Event Viewer. ---> I had to run Windows Server Backup to remove some log files associated with Exchange Database. This took care of a delay when opening Outlook 2010.

 (2) I had 2TB External USB drive attached to the SBS2011 VM via USB pass-thru and it was acting up, so I had to complete remove it from Hyper-V server and replaced it with brand new 2TB Seagate external hard drive.

So far no user has complained for a few days about the delay.

Update:
I have 2TB External Toshiba USB Drive and it was, I am not 100% sure why, causing the delay. The best I can tell is sometime when you have dead or non-responsive device connected to your computer, your computer checks for every device periodically and wait for the dead or non-responsive to respond, causing the delay.

I originally attached 2TB External Toshiba USB to SBS2011 VM via USB Pass-thru, but I would guess that it cause the problem.

Finally, I removed it from the W2012/Hyper-V server and replaced it with new Seagate 2TB Ext. HD. Since then all is fine.
