DFS Namespare

Hi,

Recently, we had bought new servers and visualize the new servers with VMWare. I have also a few physical servers still running.

One of the existing server is hosting file server named as SVR-01. This is also the DC and DNS. Previously we mapped our network share drive as direct hostname (\\SVR-01\Share)
After getting the new servers on VM, I had created 2 new file server and named them as FS-01 and FS02.

I decided to set up DFS for better future contingency if any of the file server goes down, i still have other file server to use without the need to map new network drive.

Created a namespace \\company.com.sg\dfs and followed by all the share folder. All hosted by the 2 new VM file servers and 1 existing file server.
1. FS-01 (new vm server in 2012 R2 and also configure with data deduplicated on all the share folders)
2. FS-02 (new vm server in 2012 R2 and also configure with data deduplicated on all the share folders)
3. SVR-01 (existing physical server in 2008 R2)

After setting up everything, I did a try on my own workstation and on few of my users, it works perfectly okay and nothing seem to be wrong.

After running it live to all my users, I will say about 20% to 30% of my users feedbacked that it was extremely slow OPENING the file.

From the start to the end of the DFS configuration, every single setting was pretty much straightforward. And I don't see there is a need to change any of the setting.

Or did I miss out something else?

Any advise will be appreciated ! thank you in advance.

Slow DFS, in my experience, is caused by an improperly multihomed file server, bad DNS host records/reverse lookup records, or a failing disk subsystem.  Any packet loss from one of your troubled hosts if you ping -t fs01 or ping -t fs02?

Is there common ground with these 20-30% of your users?  IE. Are they all remote, all XP, all Vista?  Do they report to a local DC?

Can you validate all your domain controllers reflect correct SRV records, that scavenging is on and working and that you don't have any poisoned or ancient host records?

Are the 2012 R2 servers fresh installs, P2V migrations, or upgrades of any kind from previous OS?

Did you make sure to uninstall any orphaned hardware during migration?
Are your NTLMv2 settings correct on the file server/clients?

Hi choward,

All my users are using Windows 7. They are all under Local Site in the same network as my DFS.

Any reference to validate are all my srv records working properly?

2012 r2 servers are fresh installed and not P2V migrations or upgrade from any kind of previous OS.

Sorry, I do not understand what you mean by uninstall any orphaned hardware. Or do you refer something like decommissioned a 2003 DC?

NTLMv2 is not define in my sec policy.

And recently I scanned my DNS with BPA.

It detected this:

DNS: Zone <zone name> is an Active Directory integrated DNS Zone and must be available
The Active Directory integrated DNS zone _msdcs.xxxx.com was not found.
 DNS: Zone _msdcs.xxxx.com is an Active Directory integrated DNS Zone and must be available

I did a check and it relate because my domain was created and start with 2000.

Follow the steps base on the link above and fix the problem by adding another primary zone (_msdcs.xxxx.com) on the forward lookup zone. After this was done, the _msdcs under honglam.com.sg was grey out.

Not so sure does this effect my dns as well.
