i tried it ... no resault!
i found must have a valid ip, but i dnt know how provide a valid ip also how set it on my pc!

Usually when you pay for internet service, your ISP sets your IP address and you can't really change it (most of the time it's not really static either so it might change every now and then), you can visit certain websites to see what your external IP address is.

No need to use exclamation points, it's not my fault you can't express yourself clearly and I'm only helping you out of the kindness of my heart so be polite.
- Check to make sure the route exists.
- Make sure ports aren't being blocked.
- Check logs on firewalls and the application.

Too much of exclamation points in lieu of periods and commas send a wrong signal/message.

How can i block internet access of some clients and allow to some with windows firewall?

Can you clarify what you're trying to accomplish. Your question doesn't really make sense as to your setup and what it is exactly you're trying to accomplish.
Do you have a server that people access over the internet? If so, what services does your server provide? In this scenario, yes, you can allow certain IP addresses through your firewall and block everyone else but depending on your service, you can also do it at the application layer.

For PPTP, I know I need to open port 1723, but the error message I'm getting when trying to connect says I need to enable GRE (Generic Routing Encapsulation.)
Does this mean opening an additional port? And what port would that be?
The difficult we do right away...
...the impossible takes slightly longer.

No it's not a port, GRE is a protocol just like TCP. And where TCP is number six and UDP is seventeen, GRE is number 47[^].
You need to dig into the manual of your firewall to find out how to enable that protocol

I don't know if this is right place to ask but I did not saw any better.
Maybe someone with high demand web sites experience can tell me where is factor for concurrent connection to IIS, when it finally give up and fails? I read some time ago that on web there is 10k problem, when any HTTP server on the market cannot handle that. It is to much IMHO for corporate complex web apps with 3 tiers and high MSSQL usage. I have found that this is approximately 1000 connections at the same time, but it still seems like too much. I cannot imagine 1000 CRUD sqls on MSSQL. Usually for single HTTP requsts there is at least 3 sql requests, usually more. So how much connection web app would handle? 100? Seems more likely, but still in my prevoius work, there was application that had hard time providing for few dozens users and abviously they not always requaired server to do something.
Any one has experience with the point when you start to need not 1 but 2 IIS servers?

IIS is not "limited" to a certain number of connections, and SQL Server should not run out of them; there's a pool, and processing is halted until there's an item available from the pool.
What caused this question? Performance-problems, or concurrency-problems?

Primarily lack of knowledge about this topic.
Secondly is requirement of new project: it has to be prepared to work on IIS web farm. I know that load balancing make sense with high-load applications. This is the reason for this question. Where is threshold for IIS when you have to switch from 1 web server to 2 or more to maintain high response times under high-load. I suspect this is dependent from complexity of code, so let's assume that it is complex and not optimal.
Also I know that IIS and MSSQL have no hardcoded limit of, lets say 101 connections, and when 102 users decide to open page, it's gonna say to him: 'no way dude!' and gonna send HTTP Code - Service Unavailable.
But there have be some kind of queue of connections and when this queue will be adding more requests then server can handle it's gonna shut itself down eventually, right?
I don't want to know exact number as it is impossible without proper stress testing of whole environment, but just a factor should be enough. Is it 10? 100? 1000? 10k?
I heard about 10k problem before but I don't know if this still an issue with all this xCore xGHz x0GB RAM server as we have now, and sources are dated: http://en.wikipedia.org/wiki/C10k_problem[^]

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.
n.podbielski wrote: I heard about 10k problem
I didn't, so I'm gonna shut up and hope that some other reader can contribute some insight into the topic.

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>

Thx for the answer.
Just have one question: your post seems like should have some links, urls inside but it does not. Did CP editor cut this off?

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,
Jassim[^]
