It's also dependent on the hardware (server and network), some IIS-settings, the "size" of your average file, and the general state of your servers' OS.

AFAIK, it doesn't shut down. If the client doesn't get a response within a set time, he'll get a time-out. Just like in a DDOS-attack, so to speak. The server processes what it can, within the limits of it's hardware.

Hi
Please read this for IIS Connection :
By default IIS7 has a limit of handling 12 concurrent requests per CPU and will queue requests above this limit. If you have some significant web load and many AJAX style requests to your server – this setting maybe very restrictive and it is hard to find out the root of the problem when you server performance is suddenly degraded.
See this post to get the picture how it can cause performance issues on your server.
Some relevant info about asp.net thread usage on IIS7 here:
asp.net thread usage on IIS7 and IIS6
Thomas Marquardt advice is to change this default limit. Recommended settings:
“All of this may be a little confusing, but for nearly everyone, my recommendation is that for ASP.NET 2.0 you should use the same settings as the defaults in ASP.NET v4.0; that is, set maxConcurrentRequestsPerCPU = “5000″ and maxConcurrentThreadsPerCPU=”0″.
This is done by adding DWORD MaxConcurrentRequestsPerCPU to the registry under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ASP.NET\2.0.50727.0
called MaxConcurrentRequestsPerCPU (DWORD). This key doesn’t exist by default. Or/and in aspnet.config section which overrides registry setting (also doesn’t exist by default) aspnet.config is here on windows 64bit:
%windir%\Microsoft.NET\Framework64\v2.0.50727\aspnet.config
You need to add the following section under “configuration” section (here I used default values) – don’t forget change maxConcurrentRequestsPerCPU to 5000.
< system.web>
< applicationPool
maxConcurrentRequestsPerCPU="12"
maxConcurrentThreadsPerCPU="0"
requestQueueLimit="5000" />
< /system.web>

Hi,
I am planning to purchase Windows Server 2012. I want to ask is it possible to have the same server contains two servers (one actual and virtual) or this feature is only available in Enterprise and dataCenter edition? and if it's possible, is it advisable? and what about the performance for both servers if I am going to have Windows Server 2012 running a Dell R720 with two processors?
Thanks,
Jassim[^]

You can have to virtual machines with one Standard-Licence. There is no Enterprise-Licence for Windows 2012 only:
Standard, Datacenter, Essential and Foundation

Hi,
I am planning a Windows Server 2012 for my company. It's an average of 100 users. Server will have MySQL, SQL Server and some file sharing.
Do you recommend to go for standard edition or enterprise edition?

If I'm not wrong there is no enterprise edition. There are licence-fees per every 2 processor-sockets.
The datacenter might be cheaper for you if you want to run mutiple virtual machines.

Hi,
I have just got my Windows Server 2012 Enterprise and I want to have an endpoint anti virus for it so I can manage all clients from the server.
I am not interested to go for Microsoft Security Solution.
I checked the market and following solutions available:
1. EST
2. Mcafee
3. Symantec
4. Kaspersky
if you had to choose from above, which one you'll decide?
Thanks,

I've used McAfee on Windows Server 2008 R2 ... for five plus years. That's two (complete?) turns of McAfee "development" cycle and although each time they've changed something in their final production interface that managed to knock something out of whack on this system, I've now grown so familiar with readjustment that using it is really easy.
For instance, filtering IPs (comes wth a firewall replacement for the windows native).
There's not a lot of bell and whistle to it ("SAas" with firewall) like say, latest Norton Antivirus (on Vista 32-bit). But at the time, McAfee was the only vendor coming through for 64-bit personal use. So, it's served me well. To date.

It's always urgent 
Did you update your connectionstring? Did the server get a new name by any chance?
|
|
|
|
|
No change for the connenctionstring.
About the Server:
I install the winserver2008 on my laptop to test this new feature.
Thanks for your reply
|
|
|
|
|
Still, I'd like to see the connectionstring. Does it contain a path, an IP?
What happens if you execute a simple "SELECT 1 FROM dual" statement from a Console-application? Can you test it to verify that the driver and database is installed correctly?

I am a little confuse about usage of CAL license. Suppose i have one database Server 2012 and on the other hand i have one application server where around 50 virtual directories which uses the sa user via web.config file to connect database server. My question is how many CALs required to purchase.

I need to invoke e .NET Managed .EXE located on a Webhost (https://..) from client machines. These clients mostly don't have the .net framework installed. Can I do this from (I know very old) VB6? I know it's old, but IT don't want to install .net framework on 600-800 clients for just one app...
Note: the .EXE application updates exchange calendar info using ExchangeWebService.
|
|
|
|
|
You cannot run .NET applications on systems that do not have .NET. You need to build an installer and let the clients install the app and all prerequisite libraries.
|
|
|
|
|
Probably I will have to create a webservice that does the job, which I can call from VB6. Unfortunatly I am stuck to this. Internally we have .net installed on the web servers (for our intranet) and the clients just are Win 7 / Xp with office installed, some policies even deny access to the "C:\" drive for standard users (not developers)

It's probably already installed; if it ain't, IT should take note that their clients aren't updated using Windows Update - which means that they're prolly missing security-packages.
Even Win2k (using the latest SP) has .NET 2.0.
