Ok. I expect to get shot over this one, so be gentle 
(gently shot ? What ?).
My.... ahem...."friend" has a customer with a SBS 2011 server.
Ok, it's overkill, but it's used purely for file serving.
Recently, they have had DNS problems regarding the loading of certain sites on their workstations. Those stations are independent of the server, the sole connection is to a shared folder
.coms were ok, but .co.uk wasn't.
I've messed around with the router DNS settings to no avail. Ie 8.8.8.8, ISP default servers etc.
Something in the back of my mind (so far back, you need Hubble to see it) reminded me of a similar incidence a few years on a SBS2008 machine, in that it was occasionally unable to resolve some Top Level Domains. (TLD's)
I found a reg fix which resolved it.
I performed the same fix on this 2011 machine : Fixed.
Questions
1. Are DNS services similar to those of DCHP, in that there should only be one service in use ?
2. Do you normally disable the DNS service in the server if you decide to use the routers ? And visa versa ?
3. Does anyone else in the UK see a similar problem with their servers ? Is this a common problem?
That SBS 2011 server ran fine for 18 months.
There was an incident that required a full nuke&pave which is where this issue arose after 3 months.
PS : That fix.....
HKLM\system\currentcontrolset\services\DNS\parameters
Create a 32bit DWORD called "MaxCacheTtl" with a value of 172800 (2 days)
Restart the DNS service.
Thank you for your attention.
